Low-Temperature Area Source Blackbody

DOMHT-70 / D2MHT-70

Product Overview

As a calibration blackbody, the low-temperature area source blackbody is calibrated with standard instruments from the Metrology Institute and can stably provide blackbody radiation with equivalent temperature of -20~70℃. It can be used for verification and calibration of non-contact temperature measurement instruments such as infrared thermal imagers and infrared cameras. It can operate in environments below room temperature, featuring high temperature control accuracy, fast heating rate, and robust product appearance.

Product Features

  • Good appearance strength;
  • The radiation surface features a pyramid design with high effective emissivity;
  • High temperature control accuracy and good temperature stability;
  • Special air duct design for fast heating and cooling rates;
  • Cooling and heating capabilities, can operate in environments below room temperature;
  • Unique air curtain design to prevent condensation on the radiation surface;
  • Calibrated with standard instruments from the Metrology Institute to ensure temperature accuracy;
  • RS232 communication interface, computer remote control, multiple temperature points correction to ensure temperature accuracy.
