Calibration of the temperature of the constant temperature and humidity test chamber requires preparation before the test. How can the test equipment be calibrated? After the temperature of the constant temperature and humidity test chamber is adjusted, the test work of the equipment can be carried out normally.
You can calibrate all working areas in the constant temperature and humidity box. You can not calibrate the equipment after replacing the test sample.
In this process, the entire working area in the constant temperature and humidity test chamber will be calibrated, and the measurement temperature and humidity point should generally be selected from the upper critical value, lower critical value and center point of the equipment usage range. The temperature and humidity points that are often used in reality can also be selected according to the needs of users, and the measurement location is set: if the volume of the device is less than 2 cubic meters, there are three humidity points and nine temperature points.
Conversely, if the volume is greater than 2 cubic meters, there are four humidity points and fifteen temperature points. If the equipment is under load, some conditions of the load should be stated on the certificate, and there is no need to recalibrate when changing the test sample, and the applicability of the constant temperature and humidity chamber can be correctly evaluated.
In this process, some comprehensive parameters of the test piece can be obtained during the equipment inspection process. Therefore, it is generally used when testing products with strict environmental requirements.
The above is an introduction to the calibration work of the constant temperature and humidity test chamber. I hope you can understand it through reading. This equipment is mainly suitable for high and low temperature reliability testing of industrial products. It is used to test the various parameters of the test piece when the components and materials of related products such as electronics, automobiles, high schools, research institutes, and military industries change in high and low temperature alternating cycles, after the device has been used for a period of time, the device needs to be calibrated in the constant temperature and humidity box so that the device can be put into use better.
