The Mikron® Calibration Source M315-HT is a two-piece portable blackbody calibration source with a digital indicating temperature controller that can be set at any temperature between ambient 5 to 450°C (9 to 842°F). Once set, the source temperature is controlled to within ±0.3°C by an internal RTD sensor. The unit has an emissivity of 1.00 at 8 to 14 µm.

The M315-HT calibration source and the digital indicating temperature controller are contained in separate housings to allow greater flexibility in positioning the instrument within an installation (e.g. long path calibration).


  • Ensure fast heat-up times and high temperature stability
  • Experience greater flexibility in positioning the instrument within an installation
  • Achieve high accuracy and repeatability
  • Guarantee the quality of your calibration source
  • Operate with high precision and resolution


  • High effective emissivity 1.00 at 8 to 14 µm
  • Large aperture (3 in diameter)
  • Excellent stability ±0.3°C per 8-hour period
  • Furnished with certificate of calibration traceable to NIST
  • RS232 serial communication included
