The Hazard Of Opening The Door During The Test Of The Temperature Humidity Test Chamber

Why don't we open the test chamber door easily in the middle of the temperature humidity test chamber?
The constant temperature and humidity test chamber is used to detect whether the product is resistant to high temperature, low temperature and low temperature can be -20 ° C, -40 ° C, -60 ° C, -70 ° C or even lower, and the high temperature can be 150 ° C. Due to the wide temperature range of the test chamber, many users of the equipment need to pay attention when doing the test:
1. If the test chamber is undergoing an extremely low temperature test of -70 °C, this time the test chamber door is opened. First, the cold air flow will overflow the test chamber. If our fingers do not make any protection, touch the wall sample of the test box. Instant frostbite, the muscle tissue of the frostbite will even be necrotic.
In addition, the constant temperature and humidity test chamber opens the test chamber door at extremely low temperature, which may cause frosting of the evaporator, which may affect the cooling speed, and may even cause damage to the compressor.
2. If the test chamber door is opened when the high temperature 150 °C test is being carried out in the test chamber, the high temperature gas will instantaneously rush out of the test chamber. If the relevant protection is not done, it is likely to burn our face if there is a burning point next to the test box. Low flammable materials may even cause a fire.
3. If the high temperature and high humidity test chamber is being carried out in the test chamber, the pressure and steam in the instrument will be very large. If the test chamber door is opened at this time, there will be high temperature and high humidity steam flushing out of the test chamber. It may cause serious burns to the operator.
Therefore, in the middle of the constant temperature and humidity test chamber operation, if it is not necessary to open the test box door, do not open the test box door; otherwise, the above adverse consequences will occur. The equipment user should fully understand the instructions before use and strictly follow the requirements.
