2.1 Description
The M390 series are high temperature blackbody calibrators that can produce a very high
temperature, high emissivity targets, and at the same time stabilize at the required temperature
within a few minutes of switch-on. The cavity is a graphite tube target which is available with a
16mm (.625") diameter, or optionally 25mm (1.00") or 38mm (1.5”) aperture with an effective
emissivity of 0.995. Target is sensed by a rapid response LumaSense infrared fiber optic
thermometer which drives a PID controller to regulate the target temperature precisely to the
desired value. The controller is mounted on the calibration source and remote set point
programming may be achieved via an RS422/485 communication port.
