Infrared thermometer optris CTlaser F2 for temperature measurement of CO2 flame gas

The infrared laser thermometer optris CTlaser F2 offers a special measuring wavelength for temperature measurement of CO2 flame gases. This makes it optimally suited for e.g. combustion processes, garbage incineration, or processes in chemical reactors.

The IR thermometer’s temperature range covers temperatures from 200°C up to 1,650°C, while the stainless steel measuring head is heat-resistant up to 85°C without additional cooling. Optional cooling and protection equipment is available, ensuring exact temperature measurement even in rough surroundings.
