Areas of application for the infrared thermometer optris CTlaser 1M / 2M

With a wavelength suitable for metal surfaces, the IR thermometers CTlaser 1 M and 2M reliably measure metals of up to 2,200°C (3992 °F).

The IR thermometers are especially popular in the metal processing industry and are employed for e.g. welding, soldering, re-forming, induction brazening, or sintering.

Additional application options are surveillance of rolling trains, tube-welding processes and forging-die forming.
The CTlaser 1M / 2M is additionally suited for measurement of metal oxides.

Infrared software optris Compact Connect included

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.
