SD-20B

The high-temperature tubular cavity blackbody radiation source independently developed and produced by the company is a special equipment mainly used for calibrating non-contact radiation temperature measuring 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


  •  Large orifice diameter, compatible with most D:S radiation thermometers;

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

  •  The temperature control instrument has multi-point independent temperature correction function;

  •  The temperature range includes ambient temperature, which can be adjusted arbitrarily between -20 ℃ and +125 ℃;

  •  The target surface adopts a corrugated structure, which can effectively improve the emissivity of blackbody radiation;

  •  The design uses a Peltier effect power module, which can quickly heat or cool the blackbody cavity, saving waiting time;

  •  Our company's unique target surface treatment technology makes the target surface temperature more uniform, 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, easy to carry.
