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.
Product Features
1. More portable, lighter. Higher precision.
2. Human-machine interface, Chinese display, touch operation, beautiful and elegant.
3. One-key temperature setting, simple operation. Rapid heating and temperature control.
4. According to customer requirements, the language interface of multiple countries and regions can be copied for easy export.
Product Advantages
1)The appearance is novel and the furnace and temperature controller are separated.
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) Isothermal blackbody cavity, only one cavity port, the cavity port radiation is evenly distributed with the spectrum, the cavity port emissivity is above 0.995, and the resolution reaches 0.1.
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.
