SD-2250

The self-developed and produced dual-cavity portable blackbody radiation source is a special equipment mainly used for calibrating non-contact radiation temperature measurement instruments such as infrared radiation thermometers and infrared thermal imagers.

The main technical indicators of the blackbody radiation source are the emissivity of the blackbody cavity, the uniformity of the target surface, and the temperature control stability.

Product Features


  • Two independent blackbody cavities with large orifice diameters;

  •  Equipped with Eurotherm 0.1-class temperature control instruments, featuring high temperature control accuracy;

  •  The temperature control instruments have multi-point independent temperature correction functions;

  •  Temperature range includes ambient temperature, from -15 ℃ to 500 ℃;

  •  The cavities are made of high-emissivity materials, which can effectively improve the emissivity of blackbody radiation;

  •  Our company's unique target surface treatment technology ensures more uniform target surface temperature, and the surface will not be damaged or chipped even after long-term use of the equipment and frequent temperature rises and falls; This product complies with JJG 856-2015 "Working Radiation Thermometers" regulations and can meet the daily verification work of infrared radiation thermometers and infrared thermal imagers in metrological institutions.

  •  With RS485 communication function for users to embed into the system; Light in weight and easy to carry.
