For calibration and verification of radiation thermometers and infrared cameras, DIAS Infrared manufactures blackbody calibration sources.
The PYROTHERM calibration radiator range includes various types with radiator temperatures from -15 °C to 1500 °C. To ensure high emissivity close to 1, surface radiators with special surface structure coatings or cavity radiators with ceramic cavities are used. Precision temperature sensors and PID control.
