SD-878

The independently developed and produced dual-chamber ultra-wide temperature range blackbody radiation source is mainly used as a dedicated device for calibrating non-contact radiation temperature measurement instruments such as infrared radiation thermometers and infrared thermal imagers.

Product Features

• The unique air curtain technology ensures that no condensation occurs during long-term low-temperature open operation. The temperature range can be freely combined from -30 ℃ to 1200 ℃.

• The cavity diameter is large, which can adapt to most D:S radiation thermometers.

• The European Continental 0.1-grade temperature control instrument is selected, featuring high temperature control accuracy.

• The temperature control instrument has multiple independent temperature correction functions

• The low-temperature cavity is a spherical structure and a tubular structure, made of high-emissivity materials, with a high emissivity.

• Our company's unique target surface treatment technology makes the target surface temperature more uniform. Even after long-term use and frequent temperature fluctuations, there will be no surface damage or chipping of the equipment. This product complies with the JJG 856-2015 "Radiation Thermometers for Work" regulation and can meet the daily verification requirements of infrared radiation thermometers and infrared thermal imagers in metrology units.
