Details

The M300 is a high standard, precision blackbody calibration source designed with a unique uniformly heated spherical cavity that achieves a near ideal emissivity of 0.998 or better.

The M300 will accurately deliver any temperature between 200 °C to 1150 °C (392° to 2102 °F). A convenient micro-processor-based, digital PID controller holds the selected temperature to within 1 °C, thus assuring high accuracy calibration.

LumaSense calibration sources have long been the gold standard to calibrate the instruments that keep your operations up and running. These blackbodies are superior because of the emissivity values, homogeneous emission areas, and a wide range of different sized apertures to adapt to the desired target area. In addition, fast heat-up times and high temperature stability are guaranteed.

The quality of our calibration sources is guaranteed by tests, burn-in times, and radiometric calibrations. On most models, a certificate is provided to document the traceability to the international temperature scale ITS90 and NIST.
