The 988 is a low cost Blackbody source introduced to meet customer requirements for a simple, cost effective but high accuracy calibrator for the calibration of thermal imagers and infrared thermometers used at temperatures around ambient.

A 70 mm diameter ridged plate is heated or cooled with an internal solid state thermoelectric heat pump. The temperature of the plate can be set from 20°C to 45°C with a resolution of 0.01°C.

Evaluation showed the advantages of fitting a stainless steel tube around the plate to give better uniformity and less sensitivity to draughts and ambient temperature effects.

Key features:

  • Ambient temperature spherical Blackbody source: 20°C to 45°C
  • Emissivity: 0.97 at ±0.02
  • Controller resolution: 0.01°C
