Optris CTRatio Infrared Ratio Pyrometer with Electronics Box

Optris CTratio 1M Infrared Ratio Pyrometer

With a completely new design for 2021, the Optris CTratio M is an innovative ratio pyrometer for the measurement of extremely high temperature metals in applications where there may be fumes and dust present and where the lens may become soiled over time.

It is also possible to measure objects that do not completely fill the sensing spot, in fact, they may be as small as just 5% of the measuring spot area and this makes it ideal where a complete view of the object is difficult or for fast-moving applications.
