Infrared Pyrometers You Can Trust

More Efficiency, Better Quality.

Accurate Infrared Pyrometers for Industrial Applications

Williamson is passionate about helping customers solve challenging temperature measurement problems so that they can improve product quality, increase process efficiency, and control costs. We recognize that each application has its own unique challenges and for over 60 years, Williamson has developed customized solutions for the most demanding industrial applications.

Wavelength Matters

So what makes us different? We believe that wavelength matters. Why does wavelength matter? Because thoughtful wavelength selection can dramatically reduce or even eliminate errors due to optical obstructions, emissivity variation, background reflections, and misalignment. With thousands of successful installations all over the world, we have developed a wealth of information on how Williamson Infrared Pyrometers can improve productivity and quality in just about any application.

MWx-AB - Aluminum Billets

MWx technology accurately measures high temperature billets where MW technology falls short. MWx pyrometer only works when looking at the side of the billet. No specific algorithm or offset is required – MWx-AB works across all alloys. Pyrometer output is set for 400-1100°F (200-600°C), but will only measure temperatures down to 575°F/300°C.
