How to choose a suitable black body:
First of all, you need to confirm the needs and goals of using black body.
Customers who need to use black bodies need to be verified by standard temperature.
1. Manufacturers of temperature-related industries
For example: ear thermometer, forehead thermometer, thermal imager, Thermopile manufacturer, distributor.
2. Research and development institutions, such as: research and development units of the above products,
3. Temperature verification institutions such as: SGS, UL and other temperature standard verification units
Different needs will cause a very big difference in the choice of models!
The purpose will determine the selected product, assuming that the product is used for mass production to verify whether the temperature isAccurate equipment, because the production line of mass production may have large temperature changes, so the equipmentThe temperature stability requirement needs to be higher, at this time, the enthalpy is largethen the external temperature
For a good black body, three parameters are very important.
1. Temperature stability.
2. Temperature resolution.
3. Temperature repeatability.
1. Temperature stability:
The temperature performance of the blackbody needs to be within a standard range. According to different requirements, it may be a single-digit stability or a temperature stability of three decimal places. Temperature repeatability.
2. Temperature resolution:
Temperature resolution is related to temperature range. High-temperature black bodies generally do not require too high a resolution. Generally speaking, blacks with a small temperature control range will have relatively high temperature resolution requirements.
3. Temperature repeatability: every time the black body is powered on, when it reaches the control temperature point, its temperature is the same as the last performance.
According to the needs of use, black body has many forms. Generally speaking, dry blackbody is easy to carry and easy to use, and it is an ideal target source for temperature calibration of temperature measuring instruments. Wet blackbody has high precision (0.001°C) and high temperature stability, suitable for long-term R&D or production, and maintains good quality temperature output even in an environment with poor temperature control.
