SD-30/50

The independently developed and produced low-temperature spherical cavity 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.

。

Product Features

• long-term low-temperature open operation;

  • Temperature range options: -50 ℃ to 100 ℃ and -30 ℃ to 100 ℃;

  • Large cavity diameter, suitable for 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 cavity has a spherical structure, made of high-emissivity materials with an emissivity better than 0.998;

  • Our company's unique target surface treatment technology ensures more uniform target surface temperature, and no surface damage or slagging will occur even after long-term use and frequent temperature rise and fall of the equipment; 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.
