Review on ACEGMET Handheld Waterproof Durability Infrared by Jonathan Clark

Bought for a house check on a new house I bought. The IR function allows you to see gaps in insulation, electric switch heating (AFCI heats up to around 105 F), hydroponic underfloor heating, chimney pipe problems, outdoor oven temperature leaks, door and window leaks, etc. Anything that could be heat or cold. Problem. The screen shows high and low temperatures and the places where they occur, as well as the average temperature on the surfaces. Battery life was very good. Really good value for money. I'm not sure what the "Warmth" rating category is for.
