Low-temperature bath surface source blackbody radiation source(-40°C~80°C)

Product Introduction

Definition of black body:

an object that can absorb all external radiation energy and radiate all its own energy at the same time.

The main technical indicators of black body:

emissivity of black body, diameter of black body cavity, temperature uniformity and uncertainty of radiation temperature. Therefore, in order to ensure the product quality of black body, black body is usually designed according to temperature segmentation. Usually what we call black body is artificial black body. The emissivity of artificial black body is close to 1, but not equal to 1.

The main function of black body is

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

Black body is mainly used in

the field of temperature measurement in industry, and the main product is black body furnace. For the calibration and verification of radiation thermometer, the comparison method is usually used, that is, through a high-stability radiation source (usually a black body radiation source) and other supporting equipment, the temperature reproduced by the standard instrument is compared with the temperature reproduced by the radiation thermometer to be tested to determine whether it is qualified or give a calibration result.

As a standard radiation source, standard black bodies are mainly used to calibrate radiation thermometers, infrared thermometers and radiation temperature sensor detectors. Our company currently has advanced black body technology, a full range of black body products with a wide temperature range. The products are small in size, light in weight and easy to carry. They are not only suitable for calibrating radiation thermometers in laboratories of metrology institutions at all levels, but can also be used for on-site calibration.
