Calibrate infrared pyrometers. Black body calibrators use a target plate, which has a high emissivity that minimizes emissivity errors.

Ambient + 10°C to 215°C temperature range blackbody provides high accuracy readings to ±0.5°C and good stability to ±0.1°C
Ambient +10°C to 400°C temperature range blackbody calibrator provides a fast heating time and a portable miniature design.
