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).
