Metis MB Pyrometer Series

Metis Self-Contained Precision On-Line Pyrometers

The Metis MB series of stand-alone pyrometers feature lead sulphide and lead selenide detectors to measure metal surfaces above 50°C. Temperature range of 130 to 700°C.



The Metis MB is a series of accurate, reliable stand-alone pyrometers are commonly used to measure the temperature of metal surfaces. 

Pyrometer Series Metis MB utilizes lead selenide detectors with filtered spectral response at relative short infrared wavelengths, and they are therefore often used to measure metal surfaces above 50°C. The emissivity of these surfaces decreases with an increased wavelength, so they offer much better performance than other pyrometers with similar low zero scale temperatures, but with longer wavelength response.

The MB pyrometer uses a fixed focus lenses.  Fixed focusing gives you control of the cone of vision and offers the possibility to measure either a small spot (focused) or the average of a bigger spot (out of focus). Fixed focus lenses with larger diameter collect more infrared energy and therefore result in smaller spot sizes.

The lenses are made of calcium fluoride CaF2  which are highly transparent in their spectral regions. If additional windows are necessary, they must offer similar optical characteristics.

The Metis MB Pyrometers are offered in 3 models with a variety of capabilities and features for maximum application flexibility.  Please see the Specifications tab above for a summary of each model.
