The most affordable thermal imager HT-102

So we come to the fact that Chi­na has mas­tered the mass pro­duc­tion of high-tech devices, mak­ing them afford­able. Now every­one can afford to pur­chase a com­pact ther­mal imager (ther­mal imag­ing attach­ment) for a smart­phone. The price is sym­bol­ic, but the ben­e­fits are a mil­lion. Well, first things first….

Why is it need­ed — to con­trol tem­per­a­ture, mea­sure tem­per­a­ture dif­fer­ences, search for heat leaks and over­heat­ing areas, local­ize hid­den heat­ing (warm floor), trou­bleshoot (for exam­ple, in heat­ing radi­a­tors), and repair equip­ment.

Sup­plied in brand­ed box.

The kit includes a stor­age case, a Type‑C to MicroUSB adapter, and instruc­tions.

The case for stor­age and car­ry­ing is very con­ve­nient — you can car­ry it with you with­out fear of dam­ag­ing the lens­es.

The size is small, a kind of attach­ment for a smart­phone

There are two cam­eras and two lens­es — for the vis­i­ble spec­trum and for the IR com­po­nent.

On the back there is a QR code for the appli­ca­tion.

Con­nects to almost any smart­phone.

Works with smart­phones in a case. Does not hang out, the length of the con­nec­tor is enough.

An adapter is includ­ed for con­nect­ing to smart­phones with MicroUSB. The adapter is not cheap, there are no back­lash­es.

Down­load the appli­ca­tion, install, con­nect.

At start­up, you need to give per­mis­sion to con­nect to the cam­era.

After that, you can work. Video and pho­to modes are avail­able, there is a com­bined mode: vis­i­ble spec­trum cam­era + super­im­posed ther­mo­gram.

The appli­ca­tion pro­vides set­tings and dis­play and mea­sure­ment modes.

Some pho­tos of tests.

Com­bined mode — pho­to from the main cam­era, com­bined pho­to, ther­mo­gram.

Advan­tages of the device: com­pact­ness, afford­abil­i­ty, bud­get, ver­sa­til­i­ty. This is an entry-lev­el ther­mal imager that can always be at hand. The price is sym­bol­ic, prices for sim­i­lar mod­els from Seek or Flir start at $400. Do not for­get about sanc­tions (ther­mal imagers are pro­hib­it­ed for export from the USA). Ver­sa­til­i­ty is achieved by com­pat­i­bil­i­ty with all Android smart­phones with MicroUSB and Type‑C con­nec­tors.

Cons of the device: low res­o­lu­tion of the matrix of 32x32 pix­els, as well as some damp­ness of the appli­ca­tion. I’m sure they’ll fix it in the future.

In any case, the ther­mal imager is the most afford­able today. Despite the short­com­ings, he has a lot of advan­tages. The most impor­tant thing is the bud­get cost and ver­sa­til­i­ty. It is suit­able for almost any appli­ca­tion, for quick­ly assess­ing a ther­mal prob­lem, trou­bleshoot­ing (heat­ing or heat leak­age).
