Pro Ratio Pyrometers
Brand: Williamson CorporationWilliamson is the only company to offer two different types of ratio pyrometer technologies: Two-Color and Dual-Wavelength.
The Dual Wavelength pyrometer has all of the capabilities of a Two-Color with some significant added benefits/capabilities.
Two-color pyrometers are an appropriate choice for many common temperature measurement applications.
However, when operating conditions include water, steam, scale, severe temperature gradients, severe or intermittent optical obstruction, flames, combustion gasses, laser energy, plasma, small targets or low temperatures, dual-wavelength pyrometers are a more appropriate choice.
Features- Six different infrared technologies including single-wavelength, ratio, and multi-wavelength designs
- A variety of wavelength options, temperature spans, and optical configurations
- A choice of traditional style and more versatile fiber optic configurations
- Advanced Ratio and Multi-Wavelength models include ESP Filtering to continuously measure intermittent targets or eliminate intermittent interferences
- A wide range of options and accessories to simplify the alignment and installation of the pyrometers as well as provide protection from hostile operating conditions
