Kalibrierstrahler M390S View

Key Features

  • Exceptional accuracy at high temperatures
  • ±0.25% of reading ± 1 °C
  • High effective emissivity of 1.0 between 0.65 to 1.8 µm
  • Rapid warm up/cool down time – only 5 minutes from ambient to 2300 °C
  • Manufactured and tested to meet rigid safety and quality standards
  • Furnished with certification of calibration traceable to NIST
  • Remote calibration set point control via RS 232


The M390S 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 cavity is a graphite tube target which is available with 25mm (1") aperture with an effective emissivity of 1.0 from 0.65 to 1.8 µm.

The M390S is a two-part Blackbody comprised of a controller section and an emitter section. The capability on the M390S is identical to the equivalent M390 with smaller size and weight due to the separation of controller from the emitter.

Target temperature is sensed by a rapid response LumaSense infrared 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 RS 232 communication port. All safety features to protect equipment and operator are easily accessible.
