What is the Impact of Repeatedly Opening the Door on the Temperature of the High-low Temperature Test Chamber?

There are several effects of repeatedly opening the door of the high and low temperature test chamber:

When conducting a test at a very low temperature of minus 70 degrees Celsius in the high and low temperature test chamber, opening the door will cause the cold airflow to spill out of the chamber. If our fingers touch the wall or sample of the test chamber without any protection, it could cause instant frostbite, and even muscle tissue may die.

In addition, opening the door of the high and low temperature test chamber at extremely low temperatures may cause the evaporator to frost, which can affect the cooling speed and even cause compressor damage.

When conducting a test at a high temperature of 150 degrees Celsius in the high and low temperature test chamber, opening the door will cause the hot gas to rush out of the chamber, and if proper protections are not in place, it can easily cause facial burns or even ignite nearby flammable objects.

When conducting a test at high temperature and high humidity in the high and low temperature test chamber, the pressure and steam inside the instrument will be very high. If the door of the high and low temperature test chamber is opened at this time, a high-temperature and high-humidity steam will rush out, which can cause serious burns to the operator.

Therefore, if it is not necessary to open the door of the high and low temperature test chamber during operation, please do not open it. If it is necessary to open the door during operation, please be sure to take relevant protective measures and use the correct method to open the door.

If the test requires multiple openings of the high and low temperature test chamber door during operation, one solution is to have two doors. The first door is an outside opening, with insulation, sealing, and an observation window. The second door is made of epoxy board or transparent hard plastic board, with a suitable-sized hole in the middle for taking samples. This effectively isolates the product from direct exposure to the air and prevents uniformity diffusion. Our company has produced multiple units of this series of products, and the market response has been positive.
