Isotech Model 975 Greybody Source
When the high accuracy of the Gemini R is not required, the Isotech model 975 Greybody source offers a cost-effective solution for calibrating and monitoring infrared thermometers.
The Greybody model 975 offers fast and accurate results with a larger detection area. The temperature sensor is just below the desired surface area and controls the temperature of the source. A custom designed surface sensor is used to set the controller calibration. A traceable certificate is supplied with each source.
