Ultra high temperature blackbody radiation source

Description :

[Product Overview]

The definition of a blackbody is an object that can absorb all external radiation energy while emitting all of its own energy.

The main technical indicators of a blackbody include its emissivity, blackbody cavity diameter, temperature uniformity, and radiation temperature uncertainty. Therefore, in order to ensure the product quality of blackbody, blackbody is usually designed in sections according to temperature. The blackbody we usually refer to is an artificial blackbody. The emissivity of an artificial blackbody is close to 1, but not equal to 1.

The main function of a blackbody is to generate standard radiation at a certain temperature. Therefore, it is mainly used in temperature measurement to calibrate various radiation thermometers, such as optical pyrometers, infrared thermometers, infrared thermal imagers, etc.

[Scope of Application]

      Blackbody is mainly used in the field of temperature measurement in industry, with the main product being the blackbody furnace. The calibration and verification of radiation thermometers usually use the comparative method, which compares the temperature reproduced by the standard instrument with the temperature reproduced by the verified radiation thermometer through a highly stable radiation source (usually a blackbody radiation source) and other supporting equipment, in order to determine whether it is qualified or provide calibration results.

As a standard radiation source, standard blackbody is mainly used for calibrating radiation thermometers, infrared thermometers, and radiation temperature sensing detectors. Our company currently has advanced blackbody technology and a wide range of blackbody products with a wide temperature range. The product has a small volume, light weight, and is easy to carry. It is not only suitable for calibrating radiation thermometers in various levels of metrology institutions and laboratories, but also for on-site calibration.
