The best FLIR thermal cameras, compared.
Top pick: FLIR M232 Best value: GOYOJO GW192A – About £129, 4.2 from 778, a stated 96×96 sensor and a span to 400°C. The award is listing per pound among rows with a large review sample, not the highest score. Updated October 2026.
A thermal camera maps surface temperature as a colour picture. In a UK house you use one to see a cold hatch, a draughty frame, a warm floor loop, or a connection that looks hotter than its neighbours. You are reading the surface in front of the lens. The picture is not a damp reading, not a view through a wall, and not a pass against the heat-loss guidance in Approved Document L. Tell a suitable camera apart by the native detector size, not the upscaled grid on the screen, by the Celsius span and the conditions on any accuracy line, and by whether the lens focuses. A phone module needs a handset. A handheld has its own screen and battery. A fixed plant head and a marine pan-and-tilt camera do not inspect a loft. You need a real indoor-outdoor gap and a cold dry spell out of the sun. Emissivity left for masonry misreads foil and steel. The order of those checks is in the [thermal camera buying guide](/hub/measuring-equipment/flir-thermal-camera/sub/flir-thermal-camera-buying-guide).

Question 1 of 2
Is this a house walk-round?
The FLIR M232 is a marine pan/tilt camera at £2,863.63, with 9 Hz in the title, IP67, and 12 V corded power at 3 W. It weighs 3.8 kg, and resolution and temperature span are not stated. The star line is 5.0 from 16 ratings. Five captured texts, none marked United Kingdom, describe night navigation on a yacht, a Garmin hook-up, and ClearCruise tracking on an Axiom. One criticism is that motion alert is set off by the bowsprit and a flag. The box includes RayNet cables, a 10 m power cable, and a top-down riser kit. The page states IP67 and does not say saltwater, and the job on those reviews is a boat rather than a loft hatch.
Pros
Cons
Best for: You are fitting a fixed marine camera to a boat monitor and a Garmin or Axiom setup.
Less suitable: A house, a phone, or any shortlist that started from a loft hatch or a radiator.
Specifications
Common questions
Is this a handheld for a house?
No. It is a marine pan/tilt camera, IP67, 12 V, with 9 Hz in the title.
What is in the box?
Camera, base seal, three fasteners, decals, RayNet cables, a 10 m power cable, a top-down riser kit, and a documentation pack.
Does the listing state saltwater use?
It states IP67. It does not say saltwater.
The Foxfighter fx1 is a handheld at £90 with a stated span of −20°C to 550°C, an 8 GB micro SD card, USB-C charging, a lens cover, and a tripod mount. Pixels, accuracy, frame rate, and NETD are not stated. It weighs 590 g and the body is plastic. The star line is 5.0 from four ratings, all marked United Kingdom in the captured set. Those four praise an easy clear image, a sturdy feel, the price, the lens cover, and the card. None states a complaint. Four happy reviews leave the detector size blank, which is the same gap the product page itself leaves open. The attribute list says indoor, while the bullets also name engines and electrical work.
Pros
Cons
Best for: You want the cheapest handheld in this set for a first look and you accept an unstated detector.
Less suitable: Any job where you must know the pixel count before you pay.
Specifications
Common questions
What resolution is stated?
None. The page asks and the bullets do not answer.
What temperature span is stated?
−20°C to 550°C.
Is a memory card included?
Yes. An 8 GB micro SD card, plus a USB-C cable and a battery.
The Thermal Master Thor 002 is a handheld with a 3.5 inch screen at £359, stating 256×192 processed to 512×384, NETD under 40 mK, and −20°C to 550°C at ±2°C. The amazon.co.uk line is 4.4 from 279 ratings, and eight of the captured texts are marked United Kingdom. Those notes praise a large readable screen, house heat-loss and brickwork checks, and day-to-day electronics work, and one UK buyer calls it good value against a much dearer camera. The battery bullet says up to 10.5 hours from 5000 mAh, while the spec line says 10 hours. UK and US reviews include units that stopped turning on after about three months, with support hard to reach. Other texts doubt the absolute number: one reports 7.8°C and −1.2°C on house surfaces on a 9°C day, and another describes drift of 6°C to 10°C after a few minutes. A case is not in the included-components line, though some reviews mention foam.
Pros
Cons
Best for: You want a stated 256×192 detector and your own screen for a house or plant walk-round, and you can accept the failure reports.
Less suitable: Anyone who needs a light phone camera, a case in the components list, or a temperature figure they will treat as a calibrated certificate.
Specifications
Common questions
What temperature span does the Thor 002 state?
−20°C to 550°C, with ±2°C on the listing.
Does the listing include a case?
Included components are the camera, a USB-C to USB-A cable, and a manual. A case is not named.
What resolution is stated?
256×192, processed to 512×384, with NETD under 40 mK.
The Fluke TC01A is an Android phone camera at £330, with 25 Hz in the title, a stated upper limit of 1200°F, and no Celsius figure and no lower limit. Pixels are not stated, it draws power from the phone, and it weighs 22 g. The star line is 4.4 from 60 ratings. None of the 27 captured texts are marked United Kingdom. Reviews call it sharper than a FLIR ONE and like that photos save on the phone, and one mentions finding a water leak under carpet. The same file says it does not work on iPhone, Windows, or Surface Pro, that a thick case needs a USB extension, and that it stopped working on Android 16 as an app issue. One unit failed a later calibration check, and a case seen in videos is not in the box.
Pros
Cons
Best for: Your phone is a compatible Android handset and you want a Fluke USB module even though the listing omits the detector size.
Less suitable: An iPhone, a buyer who needs pixels on the listing, or a temperature span you can read in Celsius before you pay.
Specifications
Common questions
Which phones does the title name?
Android smartphones. Other phones are asked about and not answered.
What temperature limit is stated?
Up to 1200°F. There is no Celsius figure and no lower limit.
What frame rate is in the title?
25 Hz. Pixels are not stated.
The GOYOJO GW192A is a USB-C phone module at £129, with a 96×96 sensor enhanced to 192×192, a stated span of −20°C to 400°C, and ±2°C or ±2% on the listing. The phone powers it at 0.31 W. It has no battery of its own and weighs 13.6 g. The amazon.co.uk line is 4.2 from 778 ratings, and eight of the first 50 captured texts are marked United Kingdom. Those notes call the app smooth when the phone accepts the plug, and they use it on windows, pipes, walls, and electrical hot spots. The same UK reviews say the USB-C plug is loose, especially on an iPhone 16, and works in one orientation only. Other texts report failure on a Pixel 9 Pro, a OnePlus 7, a Samsung S25, and an iPhone 17 that reports too much power. One UK review says Windows Defender reported Sality.AI when the unit was plugged into a PC.
Pros
Cons
Best for: Your phone is USB-C, £129 is the budget, and you can return the module if the plug will not stay in.
Less suitable: A phone the reviews already say it rejects, or a job that needs a detector the listing states above 96×96.
Specifications
Common questions
Does it work without its own battery?
Yes. The bullet says the phone powers it, at 0.31 W.
What resolution does the listing state?
A 96×96 sensor enhanced to 192×192.
Which phones does the bullet name?
Type-C iPhone and Android with OTG. The listing has no compatibility list.
This £658.80 listing is a FLIR C5 at 160×120 (19,200 pixels) sold with an MR40 moisture pen and flashlight. The star line is 4.1 from 20 ratings. The only captured review, marked United States, praises a size that fits a tool belt and a screen that shows the range and a floating target temperature. The C5 bullet states −20°C to 400°C. Focus is listed as autofocus and also as autofocus no, with a fixed aperture, so the page does not settle which is true. The attribute says not water resistant, and a case is asked about and not answered. The moisture reading in the bundle is the MR40 pen. Warranty on the listing is two years on the camera and ten years on the detector.
Pros
Cons
Best for: You want a 160×120 FLIR handheld and a moisture pen in one order.
Less suitable: You wanted the C5 alone, or you expected the thermal picture to be the moisture measurement.
Specifications
Common questions
What is in this bundle?
A FLIR C5 and an MR40 moisture pen with a flashlight.
What thermal resolution is stated?
160×120, 19,200 pixels.
Does the camera measure moisture?
The moisture tool in the bundle is the MR40 pen. The camera bullets do not say the image measures moisture.
The FLIR Edge is a wireless phone module at £304.80, with a native 80×60 sensor shown at 240×180 and its own battery rated at about two hours. Across 120 amazon.co.uk ratings the line is 4.0. Three UK reviews in the captured set describe a straightforward first setup, and other reviews use it for cold spots, drafts, and boat electrics. The same reviews keep returning to dropped connections, a lag of about one to two seconds, and a freeze about once a minute. One UK note records a sky reading of −30°C and says the unit detects nothing. The listing accuracy of ±3°C or ±5% applies only when the camera is at 15°C–35°C and the scene is 5°C–120°C. There is no case in the box, and the page says the body is not water resistant.
Pros
Cons
Best for: You already use a phone, want a FLIR wireless module for a quick walk-round, and can tolerate a short lag.
Less suitable: A survey that needs a stable live image, a stated detector above 80×60, or a camera that stays connected without restarting the app.
Specifications
Common questions
Does the FLIR Edge work with an iPhone?
The compatibility bullet says Android or iOS over Bluetooth.
What resolution does the listing state?
Native 80×60, upscaled to 240×180. The accuracy line covers a scene of 5°C to 120°C.
Is it waterproof?
The attribute says not water resistant. A 2 m drop is named in the highlight line.
The FLIR AX8 is a fixed condition-monitoring camera at £1,153.39, corded at 3 W, with no battery and a stated weight of 130 g. It offers 100 Mbps Ethernet, Modbus TCP, a built-in web server, and streams in MJPEG, MPEG-4, or H.264. Resolution, temperature span, and accuracy are not on the listing. The star line is 4.0 from two ratings. The only captured review is marked Japan and complains that the unit arrived looking second-hand. The page asks about professional installation and outdoor use and does not answer. This is a plant sensor you fit in place, and it is a poor match for a walk around a house.
Pros
Cons
Best for: You are fitting a fixed Ethernet camera to plant and you already have the missing specification from FLIR.
Less suitable: A house walk-round, a phone add-on, or a purchase that relies on this listing’s two reviews.
Specifications
Common questions
How is the AX8 powered?
Corded, 3 W. The listing says no battery.
What resolution is stated?
None. The page asks and does not answer.
How does it connect?
100 Mbps Ethernet, Modbus TCP, and a built-in web server. Streams are MJPEG, MPEG-4, or H.264.
The BSIDE HX3 is a handheld at £139.99 that states 240×240 and 25 Hz without a separate native figure, a span of −20°C to 550°C, and ±2°C or ±2%. The battery is 2500 mAh, about seven hours, and the box includes a USB cable, a case, and the battery. Emissivity and distance are adjustable, with 15 palettes. The star line is 3.8 from 10 ratings. The only captured review is marked United Kingdom and calls it very easy to use, and likes that the cell is rechargeable. That text states no complaint. The storage bullet is written as 3,0000 images, which is not a figure you can trust. Ten reviews is a thin sample beside the Thor and the GOYOJO.
Pros
Cons
Best for: You want a modestly priced handheld with a case and an emissivity control, and you can live with ten reviews.
Less suitable: A buyer who needs a native detector split from the displayed grid, or a larger UK review sample.
Specifications
Common questions
What resolution and frame rate are stated?
240×240 and 25 Hz. A separate native figure is not given.
What is the temperature span?
−20°C to 550°C, with ±2°C or ±2%.
Is a battery included?
Yes. 2500 mAh, about 7 hours, plus a USB cable and a case.
This £886.80 line pairs a FLIR C5 at 160×120 with a ONE Pro titled for Android USB-C. There is no customer-review line and no review text on the listing, so other buyers’ stars cannot steer you. The ONE bullets state −20°C to 400°C and do not state pixels. The C5 temperature span is not on this listing. MSX is named on both, and the ONE is described as using the FLIR ONE app. Case, cable, and battery are left unpublished. You are paying for two cameras. FLIR’s own UK C5 page showed £646.80 including VAT for the camera alone, which is a different offer from this basket.
Pros
Cons
Best for: You have already decided you want both cameras and can buy without a review sample.
Less suitable: A single house camera, an iPhone plug-in, or any order that depends on other buyers’ ratings.
Specifications
Common questions
What two cameras are in this listing?
A FLIR C5 and a ONE Pro titled for Android USB-C.
What resolution is stated?
160×120, 19,200 pixels, on the C5. The ONE bullets do not state pixels.
Is there a star rating on the listing?
No customer-review line is on the listing.
The FLIR ONE Pro LT listing at £301.31 is a USB-C phone camera sold with four Duracell CR2032 cells. The page does not state pixels, temperature span, accuracy, or a star rating, and the listing has no review texts. VividIR and MSX are named, and a drop of up to 1.8 m is stated. The coin cells are in the box, and the listing does not say they power the camera. FLIR’s own page describes an 80×60 ONE Pro LT as discontinued. That manufacturer figure is not printed on this amazon.co.uk listing, so it is not a fact of the basket in front of you. At a price close to the FLIR Edge, the basket gives you the name without the detector size or a review line.
Pros
Cons
Best for: You already know the ONE Pro LT specification from elsewhere and only need this USB-C bundle.
Less suitable: Anyone choosing from the listing text, or a buyer who thinks the coin cells run the camera.
Specifications
Common questions
What resolution does this listing state?
None. The page asks, and the bullets do not give pixels.
What else is in the listing?
Four Duracell CR2032 cells. The listing does not say those cells power the camera.
Is there a star rating?
No customer-review line is on the listing.
Eleven thermal-camera listings on amazon.co.uk were scored from the listing text and the review notes already on the rows, not from a lab. Stars contribute up to 30, review volume up to 20, and listing fit up to 30. Deductions come off that total and the score floors at 0. The shelf price is not in the score. It is used only to name the best value. A stated accuracy is not proved here, and a colour picture is not a damp reading, a Part L pass, or an electrical thermography report.
Amazon stars
30%Up to 30 points from the amazon.co.uk star average, as (stars ÷ 5) × 30. No star line scores 0. Two listings in this set have no star line.
Review count
20%Up to 20 points from log10 of the review count, times 7, rounded half up and capped at 20. No reviews score 0.
Listing fit
30%Up to 30 points, kept unrounded until the total: detector size (12, 8, 5, or 0), an own screen or a phone image, a Celsius span, a printed accuracy figure, and NETD when the listing states it.
Deduction allowance
20%The remaining 20 in the 100-point heading are not added. Scores already subtract them: fewer than 20 reviews, fewer than six, repeated connection faults, units dead after months, a used-looking arrival, and a focus line that contradicts itself. The floor is 0.
Start with the job, then the native detector, then the span and the accuracy conditions, then what the basket actually contains. The notes below follow that order for these eleven listings. None of the scores is a laboratory test.
A thermal camera on this shelf is the imager a UK shopper reaches when the search expects a FLIR-style tool, sold on amazon.co.uk next to other brands. You buy one to map surface temperature: hatches and frames, a cold patch that might be damp, a warm floor loop, or a hint of a hot connection. A colour picture is not a damp reading, not a Part L certificate, and not an electrical thermography report. Start with the job.
80×60 can be shown at 240×180, 96×96 at 192×192, and 256×192 processed to 512×384. The smaller figure is the one the listing states as native, where it states one at all.
About £658.80 includes an MR40 moisture pen. About £886.80 is two cameras and has no star line. About £301.31 includes coin cells the listing does not describe as the camera battery.
You image surfaces. You do not see through walls or measure air. A cold patch still needs a moisture meter before you pay for works, and Approved Document L is not a test you finish by buying a camera.
Name the job before the brand. A house walk-round, a phone module, a handheld with its own screen, a fixed plant sensor, and a marine head are not interchangeable. Then read the native detector, not the upscaled grid, then the Celsius span and the conditions on any accuracy line. NETD counts only when the page prints it. House fabric rarely needs 550°C. A listing that states only 1200°F does not give you a Celsius band.
Compare the shelf price only after you know what arrives. Entry lines in this set are about £90 to £140, mid lines about £300 to £360, and the two dear pocket baskets are bundles. The fixed camera is about £1,153.39 and the marine camera is about £2,863.63. A large review count is not a lab test. Fewer than 20 reviews, or no star line at all, is thin evidence. Stars do not raise a missing pixel count. The lowest shelf price is not the best value when the detector size is absent.
Three typical situations, each with a recommendation from this comparison.
You want a stated 256×192 detector and a 3.5 inch screen for hatches, frames, and brickwork, and you can live with reviews of units dead after about three months. The Thermal Master Thor 002 is about £359, 4.4 from 279. Confirm damp with a meter before you pay for works.
Your phone is USB-C and about £129 is the budget. The GOYOJO GW192A states 96×96, shown at 192×192, and 4.2 from 778. UK reviews say the plug is loose. Return it if the handset will not keep the connection.
The FLIR M232 is a marine pan-and-tilt camera at about £2,863.63, IP67, 12 V, with 9 Hz in the title and the picture on a separate monitor. It is not a house handheld. Read it on its own if that is the job.
In this set of eleven amazon.co.uk listings, the top pick is the Thermal Master Thor 002 at about £359. It states 256×192 before processing to 512×384, NETD under 40 mK, −20°C to 550°C, and a 3.5 inch screen, with 4.4 from 279 ratings. Reviews include units that stopped after about three months. The best value is the GOYOJO GW192A at about £129, 4.2 from 778, with a stated 96×96 sensor and a span to 400°C. The Foxfighter fx1 is about £90 and is not that pick: pixels are missing and only four reviews sit behind a 5.0 line. None of these scores is a lab test, a damp certificate, or a Part L pass.
GOYOJO GW192A
About £129, 4.2 from 778, a stated 96×96 sensor and a span to 400°C. The award is listing per pound among rows with a large review sample, not the highest score.
