Williamson PRO8155C Pyrometer

The Williamson PRO 81-55-C Pyrometer is a continuous-operation, non-contact infrared temperature measurement sensor designed for industrial temperature monitoring in heat-treatment furnaces and metal-processing equipment. It covers 750–1475 °C with a 0.15 in field of view at 12 in and operates on 24 VDC, delivering reliable infrared temperature measurement for industrial monitoring applications. This preowned unit is intended for industrial sensor installation, supporting maintenance, pyrometer replacements, and process-monitoring upgrades in furnace systems and other heat-treatment or metal-processing production lines; common replacements include Williamson PRO 120-35-F Pyrometer.
