Sharper thermal detail for more accurate electrical, leak and heat-loss diagnostics

A compact Android thermal imaging camera built for professional diagnostics, with 512x384 TISR-enhanced resolution, 25Hz live viewing and a -20℃ to 550℃ measurement range.
I bought this for property inspections and the 512x384 enhanced image is far clearer than the basic plug-in unit I had before. It picked up cold bridging around window reveals and damp patches behind plasterboard much more easily.
Fast delivery, nicely packed and working within minutes on my Android phone. I used it on a consumer unit and could spot an overheating breaker straight away. The 25Hz refresh rate makes scanning feel smooth rather than jerky.
From a technical point of view, the temperature range and app controls are excellent for field inspections. I have used it for heating surveys, radiator balancing and underfloor heating checks, and the image quality is impressive for a unit this compact.
Very capable little infrared camera and definitely sharper than the cheap thermal camera options online. My only criticism is that you do need a decent Android handset to get the best experience, but once connected it performs very well.
I was looking at a FLIR One but chose this instead because the resolution was stronger for the money. I have used it for checking draughts, loft insulation gaps and pipe runs, and it has already paid for itself in saved time.
Used mainly for diagnostic auto work in my garage. It is brilliant for checking sticking brakes and heat build-up around wiring. The app is good, though I would have liked a slightly longer cable option for awkward engine bay angles.
Test your thermal camera properly on real jobs, with easy returns if it is not the right fit.
