How should the constant temperature and Humidity Chamber be calibrated?

Abstract: 文章介绍了恒温恒湿试验箱的校准方法。主要包括三种校准方式:无负载校准、空载校准和实时测量校准。在无负载校准中,应在整个工作区域进行校准,不需要在更换测试样品后重新校准。空载校准则需在设备没有负载的情况下进行,选择的测量点包括设备使用范围的高、低临界值和中心点。实时测量和校准可以为具有严格环境要求的产品提供综合参数。正确的校准是保证设备在工业产品高低温可靠性测试中的性能和精度的重要步骤。

The calibration of the temperature of the constant temperature and humidity Test Chamber needs to be prepared before the test. How to calibrate test equipment? After the temperature of the constant temperature and humidity Test Chamber is adjusted, the test work of the equipment can be carried out normally.

1. Constant temperature and humidity Test Chamber without load calibration

You can calibrate all work areas in a constant temperature and Humidity Chamber. You cannot calibrate the device after changing the test sample.

2. The constant temperature and humidity Test Chamber is calibrated under no load

During this process, the entire working area in the constant temperature and humidity Test Chamber will be calibrated, and the measurement temperature and humidity points should generally be selected from the upper critical value, lower critical value and center point of the equipment's use range. The temperature and humidity points commonly used in reality can also be selected according to the needs of the user, and the measurement position can be set: if the volume of the device is less than 2 cubic meters, there are three humidity points and nine temperature points.

On the contrary, if the volume is greater than 2 cubic meters, there are 4 humidity points and 15 temperature points. If the equipment is under load, certain conditions of the load should be indicated on the certificate, and there is no need to recalibrate when the test sample is replaced, and the applicability of the constant temperature and Humidity Chamber can be correctly evaluated.

3. Real-time measurement and calibration of constant temperature and humidity Test Chamber equipment

During this process, some comprehensive parameters of the tested piece can be obtained during the equipment inspection. Therefore, it is usually used when testing products with strict environmental requirements.

The above is the introduction of the calibration work of the constant temperature and humidity Test Chamber. I hope you can understand it by reading it. This equipment is mainly suitable for high-low temperature reliability testing of industrial products. It is used to test various parameters of the test piece. When the components and materials of related products such as electronics, automobiles, high schools, research institutions and military industries change in high-low temperature alternating cycles, after the equipment has been used for a period of time, it needs to be kept at a constant temperature. Calibrate the equipment in the Humidity Chamber so that the equipment can be put into use better.
