Areas of application for the video thermometer optris CTvideo 3M

The video thermometer optris CTvideo 3M, like the related video pyrometers CTvideo 1M and 2M as well as the pyrometer CTlaser 1M / 2M, has been designed for measurement of metallic surfaces, and allows for easy temperature measurement during metal processing within the measurable temperature range of 50°C to 1,800°C.

Additionally, the innovative video module and the laser sight ensure a precise measuring spot adjustment even in hard-to-access processes.

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.
