DY-HT1-S high and low temperature integrated cavity blackbody furnace (-20℃-500℃)

Definition of blackbody: an object that can fully absorb external radiant energy and at the same time fully radiate all of its own energy.

The main technical indicators of the blackbody: emissivity of the blackbody, blackbody cavity diameter, temperature uniformity and radiation temperature uncertainty. Therefore, in order to ensure the quality of blackbody products, usually blackbody is designed according to the temperature segments. 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.

Product Introduction

Blackbody in industry is mainly used in the field of temperature measurement, the main product is blackbody furnace . Calibration and verification of radiation thermometers, usually using the comparative method, that is, through the high stability of the radiation source (usually a blackbody radiation source) and other supporting equipment, the temperature reproduced by the standard and the temperature reproduced by the radiation thermometer being examined, in order to determine whether it is qualified or to give the calibration results.

The standard blackbody as a standard radiation source is mainly used to calibrate radiation thermometers, infrared thermometers and radiation temperature sensing detectors. Our company now has advanced blackbody technology, a full range of products, a wide temperature range of blackbody series products. The products are small in size, light in weight and easy to carry, which are not only suitable for calibration of radiation thermometers in the laboratories of all levels of measuring organizations, but also can be used for on-site calibration.
