The M390 ultra high temperature blackbody calibrator is without parallel in its capability to produce very high temperature, high emissivity targets and at the same time stabilize at the required temperature within a few minutes of switch-on. The graphite tube target has a 16mm diameter, optionally 25mm (1.00") aperture and an emissivity of 0.995.

Target temperature is sensed by a rapid response Mikron infrared fiber optic thermometer, which drives a PID controller to regulate the target temperature precisely to the desired value. Remote set point setting is achieved via an RS422 communication port. All safety features to protect equipment and operator are easily accessible.
