The Mikron® M305 blackbody calibration source is a smart choice when portability is required and / or installation space is limited. Its 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 adds to the versatility of this calibrator.

Custom designs and variations are available upon request.


  • 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


  • 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
