Applications:

The infrared thermometers optris CT 1M and 2M are employed for temperature measurements requiring short measuring wavelengths. They precisely and reliably measure e.g. metallic surfaces in metal processing (e.g. welding, sintering) as well as metal oxides and ceramics in temperatures of up to 2,200°C.

Software:

The temperature analysis software optris Compact Connect has been developed specifically for the extensive documentation and analysis of temperature measurement data of our stationary infrared thermometers. It is license-free and included in every pyrometer shipment.
