The importance of sealing for High and Low Temperature Chamber

In fact, one of the factors affecting the test results of the high and low temperature chamber is the sealing of the equipment. It can be seen that the sealing is very important for the equipment. This is because if the sealing of the equipment is not good, the following conditions may be caused.
When the humidity test is conducted in the high and low temperature chamber, there is no way to reach the limit value of the boundary.

The cooling rate of the equipment will slow down.
The evaporator of the equipment will frost and cannot reach the limited low temperature.
During the high temperature and high humidity test, the water consumption will increase.
In fact, the results of the above situations are to affect the accuracy of the test chamber. If the test results are not accurate, then the equipment will lose its significance.

Therefore, sealing is very important for the equipment. We can also use some methods to ensure the sealing of the equipment. Before using the equipment, we should check the sealing of the equipment, and use 2~3cm paper strips to place them at the sealing position of the chamber door, Close the chamber door and pull out the paper. The more effort it takes to pull out the paper, the better its sealing is.

In addition, whether there is a test line, power line, etc., the lead hole needs to be sealed with a silicone plug, and it is necessary to confirm whether the sealing at the lead hole is good. Before the test, the power line and test line cannot be pulled out from the chamber door, and it is also necessary to confirm whether there is any foreign matter at the seal strip, and if there is any foreign matter, it needs to be cleaned, Then make sure the door is closed. When the equipment is tested, it is forbidden to open the chamber door.

Using these methods can make the high and low temperature chamber have better sealing performance and avoid leakage. In the daily maintenance, attention should also be paid to the protection of the equipment sealing strip. If the equipment sealing strip is found to be loose or aging, it should be repaired or replaced in time.

Does the high and low temperature chamber produce radiation hazards?
1. When the radiation is generated in the high and low temperature chamber, it belongs to the weak low frequency radiation, and its intensity is equivalent to the microwave oven we use. Unless long-term close face-to-face contact, it will not cause harm.

2. The design of the test instruments of the equipment is in line with the standards, and there is almost no obvious radiation source. You can safely ignore this point. Just like our common refrigerators, we believe that every household will have it. So you can completely avoid such concerns about the radiation of the equipment

3. Technicians accurately tell you that the radiation of the high and low temperature chamber is very small, even if many test equipment are placed in the same laboratory, it will not have much impact on the human body.

4. Radiation is divided into thermal radiation and electromagnetic radiation. Thermal radiation exists between two objects with temperature difference. When the test equipment is tested at high temperature, it will produce weak radiation, which will not have any impact on the human body.

5. Another point we are concerned about is that when we use the high and low temperature chamber, we can set the standard temperature limit first. Once the set temperature is exceeded, it will be automatically suspended to prevent the adverse environment from causing serious impact on the sample. Before the test, we should also check whether the sample contains flammable, explosive or strongly corrosive substances. In order to test the equipment better and accurately, the premise is to purchase the test equipment of a formal brand.
