Multi-Wavelength Pyrometer

Brand: Williamson Corporation

Williamson is the only company that offers two types of multi-wavelength pyrometers. 

The MW and MWx pyrometers are used to measure the temperature of non-greybody materials. 

These are materials for which the emissivity not only varies, but varies differently at different wavelengths.

Williamson’s multi-wavelength pyrometers use application specific algorithms to characterize infrared energy and emissivity to accurately calculate the temperature of these complex non-greybody materials. 

Algorithms have been developed and refined from extensive data collected from off-line simulations and on-line trials. 

These pyrometers also have a real-time measure of emissivity, confirming valid temperature measurement conditions and alerting you of invalid conditions that require troubleshooting.
