REED BX-500 Infrared Temperature Calibrator, 932°F (500°C)


This infrared temperature calibrator provides accurate temperatures to calibrate non-contact temperature instruments. The BX-500 is capable of generating temperatures up to 932°F (500°C) and is designed to accommodate various infrared thermometers.


  • Simply set the desired temperature in increments of 0.1°, wait for the calibrator to attain equilibrium, point the infrared thermometer at the target and compare measurements
  • For calibrating non-contact temperature instruments (infrared thermometers, pyrometers and thermal imagers)
  • Wide aperture compensates for optical infrared thermometer variations
  • Contact RTD reference well located directly behind the blackbody target to assure accurate results
