Constant temperature and humidity test chamber requirements for water

For materials that need to be tested in a humidity-resistant environment, the equipment used is a constant temperature and humidity test chamber, so water will definitely be used in the test, and it is unavoidable. However, the quality of the water also affects the equipment at any time, and in severe cases it will damage the equipment. The next one is to popularize the use of water in the constant temperature and humidity test box for everyone.

 

The higher the resistivity, the better the water insulation performance (the reciprocal of the resistance is the conductivity, and the conductivity is small). Using the superficial evaporative humidifier and the principle of the dry and wet bulb comparison method, the humidifying medium is water. Due to the large particles of humidifier in general water, long-term humidity test will definitely affect the life of the sensor in the constant temperature and humidity test chamber, and it is possible to produce a humidity sensor. In this regard, the water requirements are relatively strict, and pure water or deoxygenated ionized water is still used.

When doing the test, the water used in the constant temperature and humidity test chamber is required to be pure water, so as to facilitate the smooth progress of the test. But in fact, it is also possible to use ordinary tap water, but it is better to use insulated water. The influence of water vapor humidity on water vapor content can meet the detection requirements, but if the humidity of water vapor is too high for a long time, scale is easily formed in the water pipe, impurities in the water in the water channel are adsorbed on the surface of the product, and the water tank is not clean, resulting in equipment failure. However, if you use pure or distilled water and reset it for water making, it won't cost too much, it's better for water pipes, sinks, sinks, etc., and it won't cause a short circuit of the humidity sensor. Of course, if you can change and wash frequently, natural water will not cause much damage to the device.

 

Therefore, when customers purchase a constant temperature and humidity test box, they can first ask the manufacturer whether they can install a natural water filtration system, because after filtration, natural water can also be converted into pure water, so it is also very important to choose a manufacturer with reliable quality.
