Range: Ambient +5 to 450 °C or 842 °F

Fonte de Calibração M315-HT

Key Features

  • High emissivity
  • Excellent general purpose calibration
  • Large aperture (3” diameter)
  • High accuracy, high resolution
  • Compact, lightweight
  • Manufactured and tested to meet rigid quality control standards
  • Furnished with certificate of calibration traceable to NIST
  • RS232 serial communication (included)


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

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

Typical Calibration Applications

  • Infrared Temperature Sensors
  • Infrared Thermal Imaging Systems
  • Spectrographic Analyzers
  • Radiometers
  • Flux Meters
