See more from further away with Testo's 835-T1!
An infrared (IR) thermometer, the 835-T1 is an advanced, professional-grade instrument with 50:1 optics (allowing measurements from up to 2.0m away from the targeted object) and measurement range from -30 to +600°C. It is also possible to attach a Type K sensor (sold separately - see datasheet) to measure direct surface temperature from -50 to +600°C.
The 835-T1 comes with a 4-point laser system, allowing the user to precisely line up and calculate the temperature of an area. A built-in emissivity measurement function also ensures every measurement is reliable.
A free download of Testo's EasyClimate software is included with this thermometer for data analysis on PC.
