Williamson is a family-owned manufacturer of exceptionally accurate infrared pyrometers for industrial applications. Founded in 1951, Williamson has prided itself in making the most accurate temperature measurements in traditionally difficult to measure applications. Williamson is passionate about helping customers improve their processes through accurate and reliable temperature control. Through thoughtful pyrometer design and careful attention to wavelength selection, Williamson pyrometers can accurately view through common industrial interferences including steam, flames, combustion gases, water, plasma and oil.This careful attention to wavelength selection allows Williamson pyrometers to make temperature measurements traditionally considered “impossible” possible. Our unique wavelength selection applies to all of our visual and fiber-optic lines of noncontact infrared temperature sensors. We specialize in short-wavelength single-wavelength pyrometers, dual-wavelength pyrometers, and multi-wavelength pyrometers.
