HSFTOOLS Finder S2: A thermal imaging camera for mobile use

Most of us can’t see through walls and other materials. Even when we know what we’re looking at, like a vehicle engine, we can’t really see temperature changes with our naked eyes. That’s where the HSFTOOLS Finder S2 and S1 come in handy. They’re small thermal imaging cameras that are fully compatible with Android mobile devices.

While not everything has a temperature signature, most things do. Why does that matter? Well, if you’re trying to find pipes, electrical components, and other important fixtures in your walls — behind drywall and wood — you can use something like a thermal imaging camera to find them. The HSFTOOLS Finder S2, and its more affordable companion the Finder S1, are mobile thermal imaging cameras for that purpose. That means you can plug them into a compatible Android device and get quick readings, wherever you are. It’s an excellent tool for homeowners, DIY-ers, contractors, and professionals. HVAC professionals, for example, can use the tool to get accurate temperature readings for vents and cooling and heating components.

The Finder S2 does not use a battery and only requires a low-power draw, so it won’t drain your phone’s battery considerably. Even still, it plugs right into the USB-C port on your device and is plug-and-play. Specifications include a 256 by 192 IR resolution, 25Hz refresh rate, a temperature range of -4 degrees Fahrenheit to 752 degrees, and 40mK thermal sensitivity. It has both high and low-temperature alarms when preset levels are exceeded, plus custom level and span options and live super-resolution views with video recording support. Everything you need to get the lay of the land, well, inside the walls and behind materials, anyway.

Why would you need something like this, you might be wondering? Some unique examples include detecting hot water pipe leaks, and electrical failures, measuring reptile enclosure temperatures, HVAC maintenance, automotive and engine maintenance, and even measuring cooking or grilling temperatures.
