The high and low temperature and humidity alternating test chamber is not unfamiliar to factories that need it. It is used to detect the parameters and performance of electronic, electrical and other products after temperature and humidity changes, and to ensure the quality of the products. However, the use of the high and low temperature and humidity alternating test chamber must also follow professional standards, especially the requirements for water, which are very strict. Let's take a look at the requirements for water used in this equipment.
In the relevant regulations on water use for high and low temperature and humidity alternating test chambers, it is stipulated that pure water must be used. There are two reasons for this:
Firstly, the water particles used for humidification in the high and low temperature and humidity alternating test chamber are relatively large. If the humidity requirements are maintained for a long time, the service life of the humidity sensor will be affected. (Humidity sensors are generally divided into capacitive sensors and Honeywell sensors, which are a bit better.
However, some of their PCB boards are not made of waterproof or anti-oxidation materials. If the water quality is poor, it will cause the humidity sensor to short circuit. Or, due to the poor water quality with impurities, the water supply pipe will be blocked over time, and the heating element in the humidification bucket will short circuit.
Secondly, there is a water level switch in the humidification bucket of the high and low temperature and humidity alternating test chamber. The float in the water level switch has a magnetic rod in the middle, and the float is not made of anti-oxidation material. Therefore, if the water is not changed for a long time, the water level switch will short circuit, resulting in the inability to humidify or continuous humidification. This is not conducive to customers completing the experimental steps, and the interruption of the experiment will cause incalculable losses.
For the above reasons, it is imperative to use pure water in the high and low temperature and humidity alternating test chamber during the experiment to avoid losses. Especially for customers who frequently use humidity or conduct high temperature and high humidity tests, it is necessary to clean the water supply system and replace pure water in a timely manner after half a month or after a series of tests, in order to achieve the best service life of the machine.
The water standards for high and low temperature and humidity alternating test chambers must be strictly followed. Otherwise, it may affect the test results and cause damage to the equipment. Take good care of your equipment to bring higher benefits to your enterprise.
