Infrared thermometer optris CTlaser F6 for temperature measurement of CO flame gas

The infrared thermometer optris CTlaser F6 is an upgraded version of the pyrometer optris CTlaser F2. It has also been designed for temperature measurement of CO flame gasses, e.g. in combustion processes, in garbage incineration, or in processes in chemical reactors.

The pyrometer measures temperatures precisely between 200°C and 1,650°C. Due to the measuring head being made of stainless steel, it is heat-resistant up to 85°C without additional cooling. Also, optional cooling and protection equipment is available, ensuring exact temperature measurement even in rough surroundings.
