Details

The two-piece portable M316 Blackbody Calibration Source is an ideal unit for field calibration or verification of infrared temperature sensors.

The calibration source of the M316 is contained within a compact, hand-held housing weighing only 0.9kg (2.0 lbs.). It is connected by a flexible cable to the 0.70kg (1.5 lbs.) indicating controller, which can be carried via handle or shoulder strap. Because of the small size of the calibration source, the operator can easily position it to read the sensor, even in hard to reach locations. Consequently there is no need to remove the sensor from its position.

The M316 calibration source covers a temperature range from ambient +10 to 300 °C (572 °F), with an accuracy of ±0.5% of reading ±1°C. 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 +/-0.5 °C. The blackbody emitter mechanism uses a resistive heating device that provides long life, short stabilization times and stable temperature control. 

Typical Calibration Applications

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