Requirements for water quality in high and low temperature humidity test chamber experiments

In fact, in general, tap water can be used in the experiment of high and low temperature humidity test chamber, which can achieve the humidity effect, but if tap water is used for a long time, it is easy to produce scale in the water pipe, and the impurities in the tap water will be adsorbed to the surface of the product, the water tank will also be unclean.

In addition, the humidification particles of ordinary water are relatively large. If the humidity test is carried out for a long time, the service life of the humidity sensor will be affected, and the humidity sensor may be short-circuited. Therefore, we use high and low temperature humidity test chamber experiments to have stricter water quality requirements, using pure water or distilled water. (The volume of each preparation must be more than 20L) or the water quality with conductivity below 10μs/cm, try to ensure that the purity of the water source is as clean as possible! (The water supply tank is located at the lower part of the test chamber panel, which is convenient for supplementary water supply, and has a water recovery cycle Use the device and save water!)

Of course, we can also change the tap water frequently when using the high and low temperature test chamber for testing, and we need to pay more attention to daily maintenance and maintenance.
