Generally speaking, tap water is ok. It can achieve the effect of humidity control, but if tap water is used as humidity control water for a long time, scale will easily be generated in the water pipe, impurities in tap water will be adsorbed on the surface of the product, and the water tank will be unclean. ?
2. In addition, the long-term humidity test will inevitably affect the service life of the humidity sensor, which may cause a short circuit of the humidity sensor. In this respect, the requirements for experimental water are strict, and pure water or distilled water is used.
3. It is feasible to change and clean natural water frequently. Therefore, the daily maintenance of the test chamber is particularly important.
Extension of knowledge points:
Temperature and humidity test chamber, also known as constant temperature and humidity tester, is used to test the performance of materials in various environments, and to test the heat resistance, cold resistance, dry resistance and moisture resistance of various materials.
