$166 Mustool MT13S thermal imager doubles as multimeter

Mustool MT13S is a relatively inexpensive 2-in-1 thermal imager and multimeter with a 2.8-inch touchscreen display and an IR camera with a 192×192 resolution.

Thermal cameras used to be quite expensive, but in recent years, we’ve seen cheaper models such as the HT-102 thermal camera for Android smartphones and M5Stack T-Lite Wi-Fi thermal camera, but those integrate fairly small 32×32 and 32×24 pixels IR arrays, The Mustool MT13S provides a higher resolution 192×192 thermal camera and doubles as a 10,000-count multimeter for about $166 plus shipping on Banggood or around $177 including shipping on Aliexpress.

MT13S interface description

The thermal imager and multimeter ships with a USB Type-C cable and a user manual. At first, I was confused since I could not see the leads and connectors, but those are also included in the package and connected to the bottom side of the device based on an unboxing from one customer on Banggood. I was unable to find a detailed review for the tool, but feedback from users looks genuine and they all seem to appreciate the thermal imager function. User photos also show the device is smaller than I would have expected.

Mustool MT13S unboxing quick review

The MT13S is at least the second generation model improving on the earlier MT12S model with higher thermal imaging resolution, wider temperature measurement range, and better multimeter function with 10,000 counts instead of 4,000 counts.

It’s unclear how the USB data transmission to the host works, as I could not find any download link for a PC program. Maybe the MT13S shows as a USB drive allowing the user to download BMP files and CSV data for further processing.

The Mustool MT13S can be purchased for about $165.99 plus shipping on Banggood and  $177.23 including shipping on Aliexpress.

For some reason, Aliexpress decided to hike the price sky-high for me. 563,04€. I can buy a CAT S60 mobile with much better IR camera for this price.

Did you tray on Banggood ?

Banggod is $166 + $2.6 shipping which is much nicer

that’s what I got as well, hence why I asked 😉

Exactly. But the website is the same, it’s only a “special price” that is different.

Well, I guess I can ask my son in Georgia to buy me one and bring along next time he visits.

Ah great, it could be the best opportunity to finally put an end to my abuse of the Odroid-Go that I equipped with an MLX90640 🙂 It’s been very useful but not very handy nor quite precise in terms of pixels (32×24), though it has been fun to program. I just ordered one an BG, I’ll see when it arrives. 192×192 should be really great.

So it’s amazingly good, compared to what I used to have. The images are fluid and detailed enough so that you can recognize the forms you’re looking at. You can typically walk in a dark room looking through it, since you distinctly see objects and furniture at slightly different temperatures or emissivity depending on their material. Regularly there’s a “shutter” noise inside and the image freezes for 1-2 seconds. It really sounds like there’s a mechanical shutter or screen inside, possibly to adapt to the dynamic range it’s looking at. I have still not tested it in voltmeter mode 🙂

Any idea what the sensor is in that device?

I have not found this info, other than the fact that there appears to be many 192×192 devices arriving at the same time, so probably a fresh new sensor. Maybe I’ll open mine when it arrives 😉

There was a review (in French though) few days ago. You can see unboxing, tests, and such.
The verdict was mostly “great value for price”.

I also got a ~$500 price from that link.
Searching MT13S in AE yields a different sale from the same shop, at $250 (https://www.aliexpress.com/item/1005006521626397.html).

Looking at the “Related items” section I see an item called ET13S from a different company with the exactly the same pictures as the MT13S (the only difference if the brand name on the product), with several sellers offering prices as low as $147 (https://www.aliexpress.com/item/1005006501155225.html)

Is there any PCB measure image? (Like the TS2+ test?)
