The best Fluke multimeters, compared.
Top pick: Fluke 117 – Highest score in the set: true RMS, VoltAlert and Auto Volt at CAT III 600 V, with 4.7 from 5,113 ratings. Not CAT IV, and the amp limit is not on the listing. Best value: Fluke 15B+ – Lowest price in the set that lists 10 A AC and DC current, at £101.45, with 4.7 from 107 ratings. True RMS is not stated. The cheaper 101 lists no amp range. Updated October 2026.
A Fluke multimeter here is a handheld digital meter for voltage, resistance and continuity. It is not a current clamp, and it is not a multifunction installation tester. You match one to the work by the category and voltage printed together, by whether true RMS is stated, by whether current is listed, and by whether a temperature probe is actually supplied. CAT III 600 V covers distribution boards and socket circuits, not the origin of the installation. If a voltage bullet and the safety line disagree, follow the safety line. Those checks are set out in the [Fluke multimeter buying guide](/hub/measuring-equipment/fluke-multimeter/sub/fluke-multimeter-buying-guide). UK mains are 230 V, and these meters are battery powered. Leads need a category mark, finger guards and a short exposed tip. To prove a circuit dead, use a test lamp or a two-pole detector, and prove that instrument before and after. A non-contact screen is not that proof. Live work belongs to a competent person.

Question 1 of 2
Do you need to measure current?
For daily voltage checks around a domestic or commercial board, the Fluke 117 is the meter in this set that states true RMS, VoltAlert and Auto Volt together. It is £215.00 on amazon.co.uk, with 4.7 from 5,113 ratings, the largest review file here by a long way. Specification Met says CAT III 600 V, and the listing adds a white LED backlight. UK reviews describe it in panels and on home electrics, and several say the display is hard to read off-axis. A review on 25 June 2024 says the case was not included, and the listing has no included-components line, so the box contents are not settled from the page alone. The style name says Pack of 10 while the item count is 1. The current limit is not on the amazon.co.uk listing, though Fluke’s UK page states 10 A.
Pros
Cons
Best for: Daily checks where you want VoltAlert and true RMS at CAT III 600 V, and you can live with the display angle.
Less suitable: CAT IV work, a stated milliamp range, or a buyer who needs a case named in the box list.
Specifications
Common questions
Does the listing say the 117 is true RMS?
Yes. A bullet says True RMS technology for non-linear loads, and the title is the Fluke 117.
What safety category is printed?
Specification Met says CAT III 600 V. The maximum operating voltage field says 600 volts. CAT IV is not printed.
Is a case listed in the box?
There is no included-components line. UK reviews disagree: some describe a case or holster, and a review on 25 June 2024 says the case was not included.
The Fluke 15B+ is the first meter in this set whose listing states an AC and DC current range up to 10 A, which is the check the 101 cannot do. It is £101.45 on amazon.co.uk, rated 4.7 from 107 reviews. The safety line says CAT III 600 V, and a separate bullet says AC and DC voltage up to 1,000 V, so those two lines stay side by side rather than becoming one rating. True RMS is not stated, and a non-UK review says it is not true RMS, which matches Fluke’s own table. The box line includes the meter, TL75 leads and two AA batteries. Six UK reviews are short and positive, mentioning a larger screen and a thick rubber surround. A case and a warranty are not stated, and temperature is named without a probe in the box.
Pros
Cons
Best for: A first Fluke with a stated 10 A range when true RMS is not required.
Less suitable: Distorted AC waveforms, CAT IV work, or a buyer who needs a probe listed in the box.
Specifications
Common questions
Does the 15B+ listing say true RMS?
No. True RMS is not in the title or the bullets. A non-UK review says it is not true RMS.
What current does the listing state?
A bullet says AC/DC current measurement up to 10 A. The box line includes TL75 leads and two AA batteries.
Which voltage line should you read?
Specification Met and a bullet say CAT III 600 V. Another bullet says AC/DC voltage up to 1,000 V. Both are on the listing.
The Fluke 17B+ is the meter in the under-£130 band that puts a type-K thermocouple in the box line, so temperature is something you can start with rather than a bullet without a probe. It is £130.00 on amazon.co.uk, rated 4.7 from 62 reviews. The listing says CAT III 600 V, current up to 10 A, and also voltage up to 1,000 V, and those voltage lines do not collapse into one category. True RMS is not stated, and a non-UK review says it is not an RMS meter. A UK reviewer used the probe on an AC compressor and on exhaust temperatures, called the meter pricey, and also noted the backlight, the tone and a large display. Another non-UK review says the probe was missing from the box. A case and a warranty are not stated.
Pros
Cons
Best for: Hobby or light trade work that wants a stated type-K probe and does not need true RMS.
Less suitable: CAT IV work, or a buyer who needs the listing to say true RMS.
Specifications
Common questions
Is a temperature probe in the 17B+ box line?
Yes. Included components name a type-K thermocouple temperature probe, TL75 leads and two AA batteries.
Does the listing say true RMS?
No. A non-UK review says it is not an RMS multimeter. That is a review, not a listing field.
What category is printed?
Specification Met and a bullet say CAT III 600 V. Another bullet says AC/DC voltage up to 1,000 V.
When you need a true-RMS meter that prints CAT III 1000 V and CAT IV 600 V and also names a built-in thermometer, the Fluke 179 is the listing in this set, at £442.80. amazon.co.uk shows 4.6 from 487 ratings. The upper temperature field is 400 °C, and the style name includes backlight and temperature, though a probe is not itemised because there is no included-components line. The Amazon warranty field says 10 years, while Fluke’s UK page says lifetime, so both figures stay in view rather than one replacing the other. UK reviews praise daily use and still call the supplied leads poor or stiff. One UK review says the battery door needs two case screws. The item dimensions of 27.9 x 41.9 x 8.9 cm read like the parcel, not the meter in your hand.
Pros
Cons
Best for: True RMS plus temperature, with CAT IV 600 V printed, if you will budget for better leads.
Less suitable: A buyer who wants VoltAlert, or who expects the leads praised in the same breath as the meter.
Specifications
Common questions
Does the 179 listing include temperature?
Yes. A bullet says it includes a built-in thermometer. The upper temperature rating field is 400 degrees Celsius. A probe is not itemised.
What category is printed?
Specification Met says measurement category III 1000 V and category IV 600 V. The maximum operating voltage field is 1,000 volts.
What do UK reviews say about the leads?
Three UK reviews call the supplied leads poor, cheap or stiff. One buyer was sent TL175 leads after a complaint. Another bought TL71-1 leads.
On a battery, a fuse or a flex, the Fluke 101 gives you voltage, resistance and continuity in a pocket-sized case, and it stops there. At £89.99 on amazon.co.uk it is the lowest price in this set, with 4.5 from 1,561 ratings. The listing prints CAT III 600 V and 0.5% basic DC accuracy, with AC and DC voltage to 600.0 V, resistance to 40.00 MΩ, plus capacitance, frequency and duty cycle. Current is not in that list, so this is not the meter you buy to measure amps. True RMS is not stated. The supply line names one meter, and it does not name leads, a case or a battery. Four UK review texts praise the size and do not describe a fault, while non-UK reviews keep returning to the missing amp range, stiff leads, and one counterfeit claim.
Pros
Cons
Best for: Pocket voltage, resistance and continuity checks when you do not need to measure current.
Less suitable: Anyone who needs an amp range, true RMS, or a thermocouple.
Specifications
Common questions
Does the 101 listing include a current range?
No. The measuring parameters are AC and DC voltage, resistance, capacitance, frequency and duty cycle. Amps are not listed.
What category is printed?
The bullet says CAT III 600 V. Specification Met says IEC 61010-1:2000-1. CAT IV is not printed.
What is in the box on the listing?
The supply line says one Fluke 101. Leads, a case and a battery are not named there.
The Fluke 107 is the lighter pocket meter, listed at 200 g and £115.00, for checks where you want current named and you can live with a thin review file. amazon.co.uk shows 4.4 from 12 ratings, and the only UK review in the file calls it a very good multimeter. A bullet says CAT III 600 V, while Specification Met also prints CAT III 1000 V, so you should not treat those as one maximum. Current and voltage are named, and the listing does not state an ampere limit. True RMS is not stated. The box line is the meter, TL75 leads and a SmartStrap. A non-UK review says readings moved about on the original probes, which is a small sample rather than a settled pattern.
Pros
Cons
Best for: A pocket Fluke when you want current named on the listing and can accept a 12-rating sample.
Less suitable: A buyer who needs a stated ampere limit, true RMS, or CAT IV.
Specifications
Common questions
How much does the 107 listing weigh?
The item weight is 200 g. The box line is the palm-sized meter, TL75 leads and a SmartStrap.
Which category lines are printed?
A bullet says CAT III 600 V. Specification Met prints CAT III 600 V and CAT III 1000 V. The compatible-devices field says CAT III 600 V and below.
Does the listing say true RMS?
No. True RMS is not in the title or the bullets.
The Fluke 177 is the true-RMS listing that prints CAT IV 600 V and CAT III 1000 V, which is the category step the 117 does not take, and the price is £382.80. amazon.co.uk shows 4.2 from only three ratings, and the saved listing has no UK review body. Bullets include voltage to 1,000 V, hold, auto hold and min/max, and the warranty field says 10 years. The power field says Corded Electric, but the box line is the device, cables, a manual and papers, with no mains lead described, so that field is not a mains-powered meter. Both review texts are from outside the UK, and one complains about PVC leads rather than silicone. The current limit is not stated, and three ratings are not a ranking.
Pros
Cons
Best for: A true-RMS meter with CAT IV 600 V printed, if you do not need a temperature probe and can accept a three-rating sample.
Less suitable: Anyone choosing on UK review volume, or anyone reading Corded Electric as a mains-powered meter.
Specifications
Common questions
What category does the 177 listing print?
Specification Met says CAT IV 600 V and CAT III 1000 V. The bullets say AC and DC voltage to 1,000 V and true RMS.
Is it mains powered?
The power-source field says Corded Electric. The included-components line is the device, cables, a user manual and papers. No mains lead is described.
How many amazon.co.uk reviews are on the line?
The listing line is 4.2 from 3. The saved listing has two review bodies, from Italy and Germany, and none from the United Kingdom.
Seven handheld Fluke listings on amazon.co.uk were scored on 21 October 2026 from the listing and the review file. This is not a laboratory accuracy test. None of the seven is a clamp, and none is a multifunction installation tester. UK review texts count more heavily than non-UK texts. Deductions apply when current is missing or the amp limit is not printed, when true RMS is treated as present although the listing or Fluke’s table does not state it, when two category or voltage lines are merged into one maximum, when the 179 warranty is stated as a single figure, when the sample is very small, when the 177 power field is read as a mains-powered meter, and when UK reviews call the leads poor or the display hard to read off-axis.
Amazon stars and review volume
30%Up to 30 points from the amazon.co.uk star average and how many ratings sit behind it. UK review texts count more heavily than non-UK texts. The 117’s 5,113 ratings are not the same evidence as the 177’s three, or the 107’s twelve. Stars are not a calibration.
Category, true RMS and current
35%Up to 35 points for the category and voltage the listing prints, whether true RMS is stated, whether current is listed, and the extra the page actually names. A 1,000 V bullet does not replace a CAT III 600 V safety line. True RMS is not awarded where the listing, or Fluke’s table, does not state it.
Review sentiment
20%Up to 20 points from review notes on the display, the leads, the probe and defects. A hard-to-read display, poor leads, or a missing probe in one box score lower. A three-rating file with no UK review body cannot carry this block.
Shelf price
15%Up to 15 points for the amazon.co.uk shelf price against what that listing states. The lowest price does not win when the page lists no amp range. The 15B+ is the lowest price in this set that lists 10 A current.
Match the printed category and the quantity you must measure before the shelf price. This page keeps seven amazon.co.uk handheld listings. The score is not a laboratory accuracy test. A clamp, a two-pole detector and a BS 7671 multifunction tester are other products.
A Fluke multimeter in this comparison is a handheld digital meter, not a clamp and not a multifunction installation tester. Seven amazon.co.uk listings were captured on 21 October 2026. You tell them apart by the printed category, whether true RMS is stated, whether current is listed, and whether a thermocouple is in the box. None of these meters replaces a two-pole detector when you must prove a circuit dead.
The 101 measuring parameters are voltage, resistance, continuity, capacitance, frequency and duty cycle. Amps are not listed. If you need current on a plain sine, the 15B+ is the listing that states 10 A.
Neither listing states true RMS. Fluke’s table marks both as not true RMS. True RMS in this set is stated for the 117, the 177 and the 179. The 107 page is for work where true RMS is not needed.
VoltAlert on the 117 is a non-contact screen. GS38 prefers a test lamp or a two-pole detector to BS EN 61243-3 when you must prove voltage absent. Prove the instrument before and after.
Read the category and the voltage on the same line before you read the price. CAT III 600 V is the safety line on the 101, the 15B+, the 17B+ and the 117. It is not a rating for the origin of the installation. Only the 177 and the 179 print CAT IV 600 V and CAT III 1000 V. If a bullet says 1,000 V and the safety line says CAT III 600 V, follow the safety line. The 107 prints CAT III 600 V and CAT III 1000 V as two lines. True RMS is stated for the 117, the 177 and the 179.
After the safety line, buy the extra you will use. VoltAlert and low-impedance AutoVolt are on the 117. A type-K probe is in the 17B+ box line. The 179 names a built-in thermometer, with an upper temperature field of 400 °C, and a probe is not itemised. Pocket size favours the 101 and the 107, listed at 200 g for the 107. Then read the sample. The 117 has 4.7 from 5,113 ratings. The 177 has 4.2 from 3, with no UK review body in the file, so that average is not a ranking.
Three typical situations, each with a recommendation from this comparison.
You want one meter for daily voltage checks around a domestic or commercial board, and you still follow GS38. The 117 states true RMS, VoltAlert and Auto Volt at CAT III 600 V, at £215.00, with 4.7 from 5,113 ratings. It is not a CAT IV meter.
You work at the origin of the installation, or you want temperature on a true-RMS meter that prints CAT IV 600 V. The 179 is that listing, at £442.80, with 4.6 from 487 ratings. Amazon says 10 years and Fluke’s UK page says lifetime.
You are checking batteries, fuses and flex, and you stop at the consumer unit if you are not competent. The 101 lists voltage, resistance and continuity at CAT III 600 V, at £89.99. It lists no amp range. If you need current on a plain sine, the 15B+ is the listing that states 10 A.
In this set of seven amazon.co.uk listings, the top pick is the Fluke 117 at £215.00. The listing states true RMS, VoltAlert and Auto Volt at CAT III 600 V, with 4.7 from 5,113 ratings. The current limit is not on that listing. It is not a CAT IV meter and it is not a thermometer. Best value is the Fluke 15B+ at £101.45, the lowest price here that lists AC and DC current up to 10 A, with 4.7 from 107 ratings. True RMS is not stated. The 101 is cheaper at £89.99 and lists no amp range, so the lowest shelf price is not the best value. None of these scores is a lab test.
Fluke 117
Highest score in the set: true RMS, VoltAlert and Auto Volt at CAT III 600 V, with 4.7 from 5,113 ratings. Not CAT IV, and the amp limit is not on the listing.
Fluke 15B+
Lowest price in the set that lists 10 A AC and DC current, at £101.45, with 4.7 from 107 ratings. True RMS is not stated. The cheaper 101 lists no amp range.
