Areas of application for the video pyrometer optris CTvideo 2M

With a wavelength suitable for metal surfaces, the video pyrometers CTvideo 1 M and 2M reliably measure metals with temperatures of up to 2,200°C. They are especially popular in the processing of metals, e.g. soldering, induction brazening or in rolling trains. They furthermore, by means of their integrated video module, allow for a reliable and precise measuring field marking even in cases where the measuring objects are so hot the laser visor is not visible anymore.

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.
