DY-HT50M Blackbody Furnace(Room Temperature+5℃~500℃)

The main technical indicators of the black body: the emissivity of the black body, the diameter of the black body cavity, the temperature uniformity and the radiation temperature uncertainty. Therefore, in order to ensure the product quality of the black body, the black body is usually designed by temperature segments. Usually what we call a black body is an artificial black body. The emissivity of an artificial black body is close to 1, but not equal to 1.

Product Introduction of Blackbody Temperature Calibrator

Definition of a black body: An object that can absorb all external radiant energy and at the same time radiate all its own energy.

The main technical indicators of the black body: the emissivity of the black body, the diameter of the black body cavity, the temperature uniformity and the radiation temperature uncertainty. Therefore, in order to ensure the product quality of the black body, the black body is usually designed by temperature segments. Usually what we call a black body is an artificial black body. The emissivity of an artificial black body is close to 1, but not equal to 1.

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

Blackbody is mainly used in the field of temperature measurement in industry, and the main product is the blackbody furnace. For the calibration and verification of radiation thermometers, the comparison method is usually used, that is, through a highly stable radiation source (usually a black body radiation source) and other supporting equipment, the temperature reproduced by the standard device and the temperature reproduced by the detected radiation thermometer are used. The temperature is compared to judge whether it is acceptable or give a calibration result.

The standard black body is used as a standard radiation source and is mainly used for calibrating radiation thermometers, infrared thermometers and radiation temperature sensing detectors. At present, our company has advanced black body technology and black body series products with a full range of products and a wide temperature range. The product is small in size, light in weight and easy to carry. It is not only suitable for laboratory calibration of radiation thermometers of measurement institutions at all levels, but also can be used for on-site calibration.

Product Feature of Blackbody Radiation Source

1）The appearance is novel and the furnace and temperature controller are integrated.

2) The heating element is insulated from the shell, and special software is used for pressure-limited heating, so no high-power power transformer is required.

3) Automatic temperature rise and temperature control is adopted, which is safe and reliable, with fast heating speed and good temperature stability.

4) It is easy to use and operate, small in size and light in weight, easy to carry, and is not only suitable for laboratory calibration, but also for on-site calibration.

5) Large surface source isothermal blackbody radiation surface, the factory default emissivity is 0.95, and the emissivity can be adjusted between 0.96-0.99 if different emissivities are required.

6) The screen has built-in multi-point independent temperature correction function.

7) Automatic intelligent adjustment: Contains MH logic intelligent adjustment function, and advanced control algorithm for parameter self-tuning function.

8) Program control function, the equipment has 10 groups of different program setting interfaces reserved, one-key operation, convenient and fast, meeting the user's requirements for multiple detection points and improving the user's detection efficiency.

9) The communication interface can be customized RS232.

10) The device has a memory function, which allows it to quickly restore to the previous setting state after restarting, without the need for additional settings to start.
