Users are aware that water is required for humidity testing in constant temperature and humidity test chambers. Generally, it is recommended to use a dedicated water tank or an external water tower for water supply, as poor water quality may adversely affect the equipment. So, what are the standards and precautions for the water used in such tests? Below, we provide a detailed explanation for users.
For most user facilities, tap water is the common choice for testing in constant temperature and humidity test chambers. While this is acceptable and does not significantly impact temperature and humidity performance, long-term use of tap water can lead to scale buildup in pipes. Additionally, impurities in tap water may adhere to the surface of test samples, affecting test results. We recommend that users replace and clean the water frequently—if this is done, tap water can still be used without issue. However, if conditions permit, using purified or distilled water is preferable.
Based on the above explanation, users should pay attention to water usage in constant temperature and humidity test chambers, as improper water quality can directly impact test results and the equipment's lifespan. Only by adhering to the correct water standards for the equipment can many adverse factors caused by water quality be avoided.
