Kalibrierstrahler M310-HT

Key Features

  • Excellent general purpose calibration
  • High emissivity 1.00 effective @ 8 ... 14 µm
  • Highly uniform
  • Large aperture (3” diameter)
  • High accuracy, high resolution
  • Excellent stability ± 0.3 °C per 8 hour period
  • Manufactured and tested to meet rigid quality control standards
  • Furnished with certificate of calibration traceable to NIST
  • RS232 serial communication included


The M310-HT is a portable blackbody calibration source utilizing a digital indicating temperature controller that may be set to any temperature between ambient +5 °C to 450 °C (+9 to 842 °F). A precision RTD temperature sensor is embedded in the blackbody emitter, providing high accuracy and repeatability.

The temperature controller uses the industry standard PID algorithms to control the emitter temperature to within 0.3 °C of the set points. The blackbody emitter mechanism uses a resistive heating device that provides long life, short stabilization times, and stable temperature control.

Temperature set points are changed by pressing the up or down arrow buttons on the controller. The lower display is the set point and the upper display is the actual blackbody emitter temperature.

Typical Calibration Applications

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