Small constant temperature and humidity box operation skills

Novices operating small constant temperature and humidity chambers will encounter problems more or less, and proper tension is necessary. At the beginning of the operation, the operator feels very bad, and it is inevitable that there is some tension. This is because the operating technology is still not skilled and lacks practical experience and skills. In fact, you don't need to worry about this. As the device becomes more intelligent, the operation is very simple. Senior operators have summarized the following small constant temperature and humidity chamber operation skills:

1. Add an appropriate amount of water to the water tank and do not exceed the maximum water mark;

2. Hang the wet gauze with the humidity sensor and the lower end into the wet ball slot (wet the wet ball gauze before hanging);

3. The value of the upper limit temperature alarm value should be higher than the maximum temperature of the test to be 10 degrees, and the value of the lower limit temperature alarm value should be lower than the lowest temperature of the test to be -10 degrees;

4. The test sample is placed in the test chamber. The total volume of the test sample cannot exceed 1/3 of the total volume of the inner box. The flammable, explosive and corrosive samples are prohibited.

5. During the test, the lighting can be turned on to check the operation of the box.

6. Avoid turning the refrigeration unit on/off repeatedly within fifteen minutes.

6. During the test, it is not allowed to open the door unless necessary to avoid accidents;

7. After the test is naturally stopped according to the specified time, the power supply should be turned off in time to make the test box systems stand still;

8. After the test is completed, it is necessary to wait for the temperature to cool to a safe range before opening the door to take out the sample. If the test sample must be taken out immediately, insulated gloves must be worn to avoid burns or frostbite.

9. After the test is over, be sure to turn off the main power switch to prevent accidents such as lightning strikes.
