What are the common mistakes of the constant temperature and humidity test chamber?

NOKI Chamber am9:24

What are the common wrong operations of the constant temperature and humidity test chamber:

1. When the constant temperature and humidity test chamber is in operation, open the tailgate, causing the high-temperature cyclone to break outward and cause unnecessary damage;

2. During the installation of the environmental test box, the grounding device is not properly installed, which may cause the risk of electric shock accident;

3. When the lighting fixture is not required to observe the situation, turn on the lighting fixture inside, which will endanger its temperature control;

The experimental specifications that the high and low-temperature test chamber conforms to

The high and low-temperature test chamber is suitable for high and ultra-low temperature reliability testing of industrial products. Detect various performance parameters of the parts and raw materials of related products such as electrical and electronics, cars, motorcycles, aerospace, ships, weapons, colleges and universities, scientific research institutions, etc. under the condition of high and ultra-low temperature (alternating changes) cycle systems.

As a star product in the field of environmental testing, the high and low-temperature test box is also a machine and equipment that has the largest number of customers and the company needs a lot. The purchase of the high and low-temperature test box itself is used to test each factory’s production and manufacturing. Is the product up to standard and then mass-produced, then, as a testing instrument, which standard must the high and low-temperature test box comply with during the processing process?

Most of China’s commodities are under national standards (i.e. GB/T2423 specifications), and the specifications for high and low-temperature test chambers are: GB/T2423.1-2008 (ultra-low temperature experiment), GB/T2423.2-2008 (high-temperature experiment)

Best placement working temperature

To ensure the service life of the constant temperature and humidity test chamber, the manufacturer recommends that the equipment should be placed in a natural environment of 2510℃. The reasons for this are also various. Today, it is outlined for everyone and it is more significant. For one reason.

R23 refrigerant is a fluid density vapor, it will change with the change of working temperature, if the working temperature is low and low, on the contrary, the working temperature is high and high. Example: When the working temperature is 10~35℃, the working pressure is marked at 110~180psi under static conditions.

When working, if the working pressure is marked at 170~290psi, everything is normal. If the working pressure exceeds 300psi, it indicates that the working temperature is too high, or the heat dissipation characteristics of the machine and equipment are not good, and the high working pressure of the machine and equipment will cause overpressure, an alarm occurs, and the constant temperature and humidity test box will stop working, which will not only harm The actual effect of your experiment will continue to cause harm to machinery and equipment
