Product descriPtion

A professional instrument for multiple uses. It can be ideal for searching and checking heat bridges, heat losses, heating pipes, and underfloor heating in buildings, but it can also be used to control the temperature of various surfaces, parts of industrial machines, cars, ships, and aircraft. Thanks to the built-in memory and expandability of the microSD card, you can store a lot of photos along with the temperature data that comes with it, providing you with more material to do analysis, and reports. The built-in rechargeable Li- Ion battery allows the long-lasting operation of the instrument. The large, adjustable brightness touch screen provides easy operation even in strong sunlight. The intelligent processing unit projects data from a thermal camera onto a camera image transmitted by a conventional camera. Touching a point on the display will display the temperature data for that area. The variable 9 temperature scales result in easy-to-read temperature differences.
