The best tachometers, compared.
Top pick: Klyk non-contact photo tachometer Best value: YOOREAL YR-HM011F hour tachometer – £13.99 with a replaceable CR2450, 4.4 from 259 reviews, and a printed 10 rpm step. Three patterns only, and no IP code. Updated October 2026.
A tachometer is either a handheld meter for a spinning shaft or a small inductive hour meter for a petrol engine, and those are different purchases. A lathe, drill, fan, pulley, or record deck needs a photo meter or a 2-in-1 with a contact tip. A petrol mower, generator, or saw needs a meter that wraps or clips the spark-plug lead and stores hours. A diesel engine, a battery tool, or a mains motor will not drive a spark-wire meter. Inductive listings usually print 0–20,000 or 0–25,000 rpm and a 10 rpm step. Choose the family in the [tachometer buying guide](/hub/saw-accessories/tachometer/sub/tachometer-buying-guide) before you compare models. Rpm and hours for a petrol saw alone sit in the [chainsaw tachometer](/hub/saw-accessories/chainsaw-tachometer) comparison. A handheld photo meter counts a reflective mark with a beam, usually from 50 mm to 500 mm. The 2-in-1 models add a contact tip, and that tip has a lower rpm ceiling than the photo range on the same body.

Question 1 of 2
What will you measure?
The Klyk Digital Tachometer-1 is an £11.99 laser photo meter that prints 2.5–99,999 rpm from 50–500 mm and stores maximum, minimum, and last readings. It ranks 1 in Industrial Tachometers on amazon.co.uk, but that rank sits on a 5.0 star line from a single review with no review text. There is no UK opinion to report, positive or negative. The listing also leaves the basics open: the bullets mention batteries and a pouch, while the included-components line names only the tachometer, and the question about batteries is unanswered. The printed weight of 20 g is unusually low for a handheld body, and no accuracy figure or laser class is stated. Treat it as an unproven £12 photo meter rather than the best seller its rank suggests.
Pros
Cons
Best for: A buyer happy to try an unreviewed £12 photo meter on a workshop motor and return it if it misbehaves.
Less suitable: Anyone choosing on evidence, since the rank and the 5.0 stars rest on one review.
Specifications
Common questions
Do batteries come in the box?
The listing question is unanswered. Included components say “Digital Tachometer” only. The bullets also name reflective tape and a pouch.
What range is printed?
2.5–99,999 rpm, non-contact, from 50 mm to 500 mm.
How many reviews support the 5.0 score?
The star line is 5.0 from 1 review. The raw file has no review text.
The YOOREAL YR-HM011F is a £13.99 inductive hour meter that prints 0–20,000 rpm in 10 rpm steps, three firing patterns, a 0.5 second refresh, and a replaceable CR2450 cell. It names chainsaws in the title alongside mowers, generators, and outboards, and holds 4.4 stars from 259 amazon.co.uk reviews. UK buyers found it easy to fit and extended the 1.75 m wire where needed, and one used it to check a car’s own tachometer. Total hours run to 99,999 h with a reset, a separate service timer goes to 9,999.9 h, and the data survives a cell change. The weak point is the battery door: one UK reviewer rejected the waterproof wording because the compartment had no rubber seal, and another said a cell lasted two weeks. Three patterns cover common single-cylinder setups, but you still have to pick the right one.
Pros
Cons
Best for: A petrol chainsaw, mower, or generator where you want hours, a service reminder, and a cell you can change for about £14.
Less suitable: Wet outboard use, since there is no IP code and the battery door is unsealed, or engines that need more than three patterns.
Specifications
Common questions
Can you replace the battery?
Yes. The listing says a replaceable CR2450, with an insulation sheet for transit. Data is kept after a cell change.
Does the title name a chainsaw?
Yes. It also names a lawn mower, generator, outboard, snowblower, jet ski, and dirt bike.
Is an IP rating printed?
No. The listing says a whole housing and a rear O-ring. It does not print an IP code.
The YOOREAL YR-HM011E is an £11.99 inductive hour meter that wraps the spark-plug lead and prints 0–20,000 rpm, three firing patterns, and a 0.5 second refresh. With 4.3 stars from 981 amazon.co.uk reviews it has the largest review sample in this table and ranks 1 in Lawn Mower Hour Tachometers. UK buyers fitted it to bikes, mowers, a jet ski, a wood chipper, and a generator, and used it for carburettor pilot screws and for tickover against top revs. One UK reviewer saw 3,000 rpm on the meter against 6,000 on the bike’s own tachometer until the wasted-spark setting was chosen, which is a setup issue rather than a fault. The CR2450 cell is sealed, so a flat battery means a new meter, and the adhesive pad let go on a mower until the reviewer used the screw holes. One UK outboard owner reported the housing broke after about 16 hours, and the listing prints no IP code behind its weatherproof wording.
Pros
Cons
Best for: A petrol mower, generator, or small bike where you want hours and a service reminder for about £12 and can accept replacing the meter when the cell dies.
Less suitable: Anyone who wants to keep the meter for years, or who needs a printed IP rating for an outboard or a wet machine.
Specifications
Common questions
Can you replace the battery?
No. The listing says the built-in CR2450 cannot be replaced. Data is kept when the LCD is shut down.
Does this title name a chainsaw?
No. It names a lawn mower, scooter, dirt bike, tractor, generator, compressor, marine engine, motorcycle, snowblower, and pressure washer.
What speed range does it state?
0–20,000 rpm, three firing patterns, and a 0.5 second refresh. It does not state an rpm accuracy step.
The DANOPLUS DP-401 is a £29.99 2-in-1 handheld meter that prints 3–99,999 rpm by laser from 50–500 mm, 3–19,999 rpm by contact, ±0.05%, and a 0.8 second sample above 60 rpm. It has a backlight, data hold, and maximum and minimum, and comes with two reflective tapes, four accessories, and a manual. With 4.3 stars from 249 amazon.co.uk reviews it has the strongest star line and sample among the 2-in-1 meters here. One UK buyer used it at work on motor rpm and lift speeds and said it seemed as accurate as a dearer calibrated meter, which is one report rather than a certificate. Others found the instructions poor or missing, and one UK buyer called it too delicate and not fit for purpose. There is no case in the box, so one reviewer 3D-printed one.
Pros
Cons
Best for: Regular workshop or maintenance checks on motors, fans, and drives where you need both modes and a stated accuracy figure.
Less suitable: Rough site use without a case, or petrol hour logging.
Specifications
Common questions
What accuracy does the listing print?
The bullet prints +/-0.05%. That is the seller’s claim. This comparison did not calibrate the meter.
Is a case included?
No. Included components are the tachometer, two reflective tapes, four accessories, and a manual. A UK review printed a case.
What are the two ranges?
Non-contact 3–99,999 rpm and contact 3–19,999 rpm, from 50–500 mm, with a 0.8 second sample above 60 rpm.
The NInE-ROnG RL-HM032R is an £18.59 inductive hour meter for petrol engines that prints 0–20,000 rpm, eight firing patterns, a selectable 0.5 or 1.0 second refresh, and IP65. It is the only meter in this table with a printed IP code, and it ships with a replaceable CR2032, velcro, cable ties, and screws. With 4.2 stars from 543 amazon.co.uk reviews, UK owners report it still working on a garden tractor and a mower through vibration, heat, and rain, and others used it on an Aprilia scooter, a Honda Izy, an outboard, and while adjusting a STIHL multi-tool carburettor. Total hours cannot be reset, while a job timer and a 200 h service countdown can. The cell is the weak spot in use: leaving the display on flattened it within two weeks for one UK buyer, and another could not reseat it after pulling it out with its sleeve. One UK motorcycle never read correctly.
Pros
Cons
Best for: A petrol garden tractor, mower, or outboard that lives outdoors, when you want a printed IP rating and a cell you can change.
Less suitable: Anyone who wants to reset total hours, or who will forget to let the display sleep.
Specifications
Common questions
Is a waterproof rating printed?
Yes. The bullet prints IP65. That is a listing claim, not a test recorded here.
Can you change the battery?
Yes. A CR2032 is included and the listing treats it as replaceable.
Does the title name a chainsaw?
No. The title says petrol engine. A UK review used it on a STIHL multi-tool.
The GAIN EXPRESS TAC-401 is a £29.90 2-in-1 handheld meter that prints 3–100,000 rpm by laser from 50–500 mm and 3–19,999 rpm through a detachable contact tip. It adds data hold, maximum and minimum, a backlight with a low-battery indicator, and an auto-off after 15 minutes that you can disable. The box includes two reflective tapes and four measuring accessories. It holds 4.2 stars from 62 amazon.co.uk reviews, but only two review texts are from the UK: one said both modes worked, and the other found it over-complicated and preferred an analogue meter. With so few UK reports, praise and criticism are single opinions rather than a pattern. The UK bullets state neither the battery nor an accuracy figure.
Pros
Cons
Best for: A workshop user who wants a 2-in-1 with a backlight and an auto-off they can switch off, at about £30.
Less suitable: Anyone choosing on UK review evidence, or someone who prefers an analogue dial.
Specifications
Common questions
What are the two rpm ranges?
Non-contact 3–100,000 rpm and contact 3–19,999 rpm. Distance printed is 50–500 mm.
Is a carry case included?
The listing asks the question. The included line lists the meter, two reflective tapes, and four measuring accessories, not a case.
Which battery does the UK listing name?
It does not. Leave the cell as unknown from this extract.
The YOOREAL YR-HM011J is a £17.89 inductive hour meter that clips onto the spark plug instead of wrapping the lead, and prints 0–25,000 rpm in 10 rpm steps with nine firing patterns. It also logs a non-resettable total, a job timer, a service countdown, the number of engine starts, and a maximum rpm, with a red over-speed backlight. On amazon.co.uk it holds 4.1 stars from 171 reviews, and UK buyers called it simple, useful, and essential for checking and setting a machine’s revs once the instructions were worked out. That caveat recurs: UK reviewers found the instructions vague and the menu busy for someone who only wanted an rpm figure. One unit would not power up even with a new battery and was returned. The battery is replaceable, but the cell type is not stated, and the waterproof claim has no IP code.
Pros
Cons
Best for: A mower, generator, or motorcycle where you want the most logging and pattern choice in this table and do not mind learning the menu.
Less suitable: Anyone who only wants a quick rpm figure, or who needs a printed IP rating.
Specifications
Common questions
Do you wrap the plug lead?
The bullet says no. It uses an alligator clip on the spark plug, with a 1.75 m lead.
Can total hours be reset?
No. TOT cannot be reset. An initial value can be set only if the engine has run for no more than one hour.
Is the battery replaceable?
Yes. The cell type is not printed. A low-battery reminder is listed.
The Mengshen HT-522 is a £24.99 2-in-1 handheld meter with a laser range of 2–99,999 rpm, a contact range of 2–20,000 rpm with four heads, and surface speed and length in metric and imperial units. It is the only listing here that states surface speed, and it ships with its 9 V battery. On amazon.co.uk it holds 4.1 stars from 90 reviews, and all 16 review texts in the file are from the UK. Those buyers checked a CNC router, a tractor PTO, and a boat engine against its dashboard gauge, and one read 1,425 rpm on a 1,400 rpm motor. The two modes split opinion: one UK buyer found the optical pickup failed on a small shaft while contact worked, another found non-contact read far too high, and one returned a unit whose contact mode did not work. The rubber contact tip can fly off and get lost, and the instructions were called uninformative.
Pros
Cons
Best for: Workshop shafts, belts, and conveyors where you need both modes and a surface-speed reading for about £25.
Less suitable: Petrol hour logging, or anyone who wants clear instructions out of the box.
Specifications
Common questions
Does it measure surface speed?
Yes. The bullets list m/min, inch/min, feet/min, and yard/min, plus length.
Is the battery included?
Yes. The included-components line says a 9 V battery.
Which model number is printed?
The title says TH-522. The model field says HT-522.
The QWORK WD45221 is an £11.98 laser photo meter that prints 2.5–99,999 rpm from 50–500 mm, with an 18 mm five-digit LCD. It holds 3.8 stars from 93 amazon.co.uk reviews and sits at rank 3 in Industrial Tachometers. UK buyers used it to set idle and cutting speed on a ride-on mower and to check a lathe and a floppy-drive spindle, and one said it does the job if you already know roughly what the rpm should be. The recurring complaint is an unstable optical reading: one UK reviewer saw the figure jump from hundreds to thousands at the same speed even after black tape, and others found the number depended on where they aimed. One laser stopped after about 31 days, and a UK buyer warned that the beam and its reflection off the chuck seemed very strong. The listing prints no accuracy figure and no laser class, and the 6F22 9 V battery is not in the box.
Pros
Cons
Best for: A rough rpm check on a large, matt pulley or a mower when you already know the expected speed and want to spend about £12.
Less suitable: Small or shiny shafts, lathe chucks, and any job where you need one stable figure you can write down.
Specifications
Common questions
Is a battery included?
No. The title and the specification say one 6F22 9 V battery is not included.
What range does the listing print?
2.5–99,999 rpm, with a stated measuring distance of 50–500 mm.
Does the title name a chainsaw?
No. It is a non-contact laser photo RPM meter.
The NAMVO meter is an £11.99 non-contact photo tachometer that prints 2.5–99,999 rpm, ±(0.05% + 1 digit), and a 0.8 second sample above 60 rpm. It is the only £12 photo meter here that states an accuracy figure, and it stores the last, maximum, and minimum reading. On amazon.co.uk it holds 3.8 stars from 63 reviews, but only four of the review texts in the file are from the UK. Those UK buyers checked lathe speeds, a record deck, and a washing-machine spin, and said it did the job. The criticism is about power: one unit would not switch on, and another smoked when the 9 V battery went in the wrong way round, with no safeguard the reviewer could see. The 6F22 cell is not included, so check the polarity before you fit one.
Pros
Cons
Best for: Occasional workshop checks on a lathe, a turntable, or a fan when you want a stated accuracy figure for about £12.
Less suitable: Petrol engines, contact work on a small shaft, or anyone who wants a battery in the box.
Specifications
Common questions
Is a battery included?
No. The listing says a 6F22 9 V battery is not included.
What measuring distance is printed?
Both 50–200 mm for the LED and 50–500 mm for the laser are printed on the same listing.
Does it include a contact tip?
No contact range is printed. It is a non-contact photo tachometer.
The POFET 1672 is a £13.99 inductive hour meter that reads beside the spark-plug cable, names chainsaws, lawn mowers, and motorcycles in the title, and counts hours to 10,000 before it returns to zero. It holds 3.8 stars from 14 amazon.co.uk reviews, and only two of the texts in the file are from the UK. One UK buyer used it to check and adjust a chainsaw and was pleased. The other saw about 1,400 rpm on a mower they expected near 2,900, roughly half, and the listing prints no firing-pattern setting that would correct that. Its rpm line of up to 99,999 rpm is far above the 20,000–25,000 rpm the other inductive meters print, and no refresh rate or accuracy is given. The battery is described as easy to change, but the cell type and whether one is in the box are not stated.
Pros
Cons
Best for: Logging hours on a petrol saw or mower where the rpm figure is a rough guide rather than a setting target.
Less suitable: Carburettor work where you need a believable rpm, and engines whose spark pattern you would need to select.
Specifications
Common questions
Does the title name a chainsaw?
Yes. The title also names lawn mowers and motorcycles.
Can the battery be changed?
The bullet says the battery is easy to change. The cell type is not printed, and the question about whether a battery is included is unanswered.
How many firing patterns does it list?
None. The tachometer claim printed is up to 99,999 rpm, and hours run to 10,000 before returning to zero.
The Asixxsix SM6236E is listed at £43.07 as a handheld laser and contact meter with a five-digit 18 mm display, which makes it the dearest row in this table. The amazon.co.uk extract prints no rpm range for either mode, no distance, no battery, and no weight. It holds 2.8 stars from two reviews, and the only UK text says the readings were not consistent. Without ranges you cannot compare it with the DANOPLUS or GAIN EXPRESS meters at about £30, which print both. The material field says PLA and PE, which reads as listing text rather than a confirmed housing spec. On this evidence it costs more and tells you less than any other handheld here.
Pros
Cons
Best for: Only a buyer who already knows the SM6236E and its ranges from another source.
Less suitable: Anyone comparing on the listing, since the cheaper 2-in-1 meters print the figures this one leaves out.
Specifications
Common questions
What rpm range does it state?
None. The title says a handheld laser and contact meter with a 5-digit 18 mm display, and the specification block has no range.
What did the UK review say?
The only UK text says the readings were mixed and not consistent.
Is a battery named?
No. Battery, weight, and dimensions are not in the extract.
We read 12 amazon.co.uk tachometer listings dated 16 October 2026 and the public UK sources below. The editorial score is not the star rating times 20, and it is not a laboratory or calibration result. Handheld photo meters and inductive hour meters are scored on the figures each family prints. Price is not part of the score. A high score means the listing states the setup figures, the battery story, and UK review text that describes a real job. The top pick and best value labels follow that score. They do not mean an hour meter beats a photo meter.

Choose the family before the model. A shaft needs a photo or 2-in-1 meter. A petrol engine needs an inductive hour meter. The printed range, the cell, and any IP code come after that split.
A tachometer in this comparison is one of two tools. A handheld photo meter counts a reflective mark with a beam, usually from 50 mm to 500 mm. The 2-in-1 models add a contact tip, and that tip has a lower rpm ceiling than the photo range on the same body. An inductive hour meter wraps or clips the spark-plug lead, shows rpm, and stores hours for servicing a mower, generator, bike, or saw. Photo meters in this set are the QWORK, NAMVO, and Klyk listings.
A photo meter does not store hours on a petrol saw, and an inductive meter does not read a lathe or a mains motor. Diesel engines and battery tools are outside both spark-lead meters.
The other inductive listings print 0–20,000 or 0–25,000 rpm. The POFET line of up to 99,999 rpm sits far above that band, and one UK mower read about half the expected speed with no pattern setting printed.
A wasted-spark or wrong pattern can show about half the rpm. Change the pattern before you adjust the mixture. On a photo meter, tape on bare shiny metal and aiming at a chuck made readings jump.
The first split is the machine, not the star rating. A lathe, drill, fan, pulley, or record deck needs a photo meter or a 2-in-1 with a contact tip. The beam counts a reflective mark, usually from 50 mm to 500 mm. The contact tip is for a shaft you can touch, and its rpm ceiling is lower than the photo range on the same body. A petrol saw, mower, or generator needs an inductive hour meter on the spark-plug lead. That meter shows rpm and stores hours.
Photo listings in this set often print about 2.5–99,999 rpm, and some add ±0.05% + 1 digit. Inductive listings usually print 0–20,000 or 0–25,000 rpm and a 10 rpm step. A line of up to 99,999 rpm on an inductive meter, as on the POFET, does not match that band and is not a better specification. Firing patterns matter on a spark-lead meter. Three patterns, on the YOOREAL YR-HM011E and YR-HM011F, cover fewer engines than eight on the NInE-ROnG or nine on the YR-HM011J.
Three typical situations, each with a recommendation from this comparison.
You need rpm on a motor, fan, pulley, or drive, and you will use both a beam and a contact tip. The DANOPLUS DP-401 prints both ranges and ±0.05%, with 4.3 from 249 reviews at £29.99. It does not log petrol engine hours, and it has no case.
You want hours and rpm on a petrol mower, tractor, or outboard, with a cell you can change and a printed IP code. The NInE-ROnG RL-HM032R states IP65, eight firing patterns, and a replaceable CR2032 at £18.59. Total hours cannot be reset, and the display should be allowed to sleep.
You want an inductive hour meter for a petrol chainsaw, mower, or generator, and you want to change the cell yourself. The YOOREAL YR-HM011F prints 0–20,000 rpm in 10 rpm steps and a replaceable CR2450 at £13.99, with 4.4 from 259 reviews. It has three firing patterns and no IP code.
There is no single tachometer for a lathe and a petrol engine. The top pick on the editorial score is the NInE-ROnG RL-HM032R at £18.59: IP65, eight firing patterns, and a replaceable CR2032. That score is about how completely the listing is documented. It is not a calibration, and it is the wrong family for a shaft. The best value is the YOOREAL YR-HM011F at £13.99, with a replaceable CR2450, 4.4 from 259 reviews, and a 10 rpm step. It has three patterns and no IP code. For motors, fans, and drives, use a photo or 2-in-1 meter such as the DANOPLUS DP-401.
YOOREAL YR-HM011F hour tachometer
£13.99 with a replaceable CR2450, 4.4 from 259 reviews, and a printed 10 rpm step. Three patterns only, and no IP code.
