There are three distinct Single-Wavelength pyrometer technologies: Short-Wavelength, Long-Wavelength, and Specialty-Wavelength. Single-Wavelength pyrometers are preferred when appropriate due to simpler, lower-cost technology. For most applications, select the shortest wavelength compatible with the measurement conditions and desired temperature span. Specialty wavelengths may be necessary depending on the optical and emissivity properties of the target. No matter your application, Williamson has the industrial infrared thermometer technology to suit your needs.

Williamson is the only company that can offer two different ratio technologies: two-color and our unique dual-wavelength. Ratio pyrometers are different from single-wavelength pyrometers because they measure infrared energy at two wavelengths instead of one. The ratio of energy between the two measured wavelengths is then converted into a temperature value. This method of measurement allows ratio industrial infrared pyrometer technology to compensate for emissivity variation, partially filled fields of view, and optical obstructions.

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.
