Key Features

  • Easily moved when needed. Weighs only 17.8 kg. (39.3 pounds)
  • High accuracy ±0.2% of reading ±1°C
  • High emissivity 1.0 effective at 0.7 to 1.8 µm T>=230°C, 1.0 at 8-14 µm T<230°C
  • Manufactured and tested to meet rigid quality control standards
  • Furnished with certificate of calibration traceable to NIST             
  • RS232 (standard) or RS485 (optional) serial communications port


The M360 blackbody calibration source uniquely combines portability with wide temperature range from 50° to 1100 °C (122 °F to 2012 °F), high emissivity, and remarkable resolution. An optional precision machined aperture wheel assembly allows different sizes of aperture diameter for applications requiring specific radiating aperture or for verifying field of view of radiometers or infrared thermometers.

The source and the controller are housed in separate modules, which allow the source to be positioned in a location remote from the controller such as in an environmental test chamber, or to be used in tests which involve long path lengths. Each module is fitted with a carrying handle and can be comfortably carried to manufacturing plant or field research locations.
