Mikron M305 Blackbodies


Compact, General Purpose Blackbody Calibration Source, 100 to 1000°C

The Mikron® M305 blackbody calibration source designed for applications where portability is required and / or installation space is limited. The M305's spherical, metal cavity design yields an emissivity of 0.995 over the temperature range of 100 to 1000°C (212 to 1832°F) with an aperture of 25 mm (1 in). An integrally mounted PID controller allows for easy, precise control of desired temperature setpoints.


  • Integrally mounted PID controller
  • Furnished with certificate of calibration traceable to NIST
  • RS232 (standard) or RS485 (optional) serial communications port
  • High emissivity 1.0 effective at 0.7 to 1.8 µm T ≥ 230°C, 1.0 at 8 to 14 µm T < 230°C


  • Easily move, weighs only 25 kg (55 lb)
  • Meet rigid quality control standards
  • Achieve ideal emissivity and accuracy
  • Rely on fast heat-up times and temperature stability
