Operating procedure of constant temperature and humidity testing chamber

Operating procedure of constant temperature and humidity testing  chamber
The constant temperature and humidity test chamber simulates the temperature and humidity changes in natural weather, and can also achieve extreme high temperature and low temperature scenarios, and carry out high temperature, low temperature, wet and dry climate resistance tests on the test items. After the test items in nature through temperature changes and air humidity changes, there will be some aging phenomenon, which may affect the performance of the item, and the constant temperature and humidity test chamber is used to simulate this environment to accelerate the aging results of the item, and then improve the performance of the product according to the aging situation.

When conducting the constant temperature and humidity test chamber, the test should be carried out in strict accordance with the process on the operating instructions, so as to avoid the inaccurate test results. Because the constant temperature and humidity test chamber has high temperature and low temperature test, it must comply with the test operation specifications to carry out the test, so as not to burn the staff due to high temperature, or affect the normal work of the sensor due to high temperature and low temperature.

The test procedure of the constant temperature and humidity test chamber of the assistant blue instrument is as follows:

1, open the test box door, first put the test sample rack support bar into the box bayonet, and then place the material rack on the support bar,

2. Place the required test materials on the material shelf (in order to ensure that the tested materials are consistent with the temperature and humidity in the test box, a certain distance should be maintained between the test samples, and the air outlet and return air outlet of the machine can not be blocked. The total volume of the materials should not exceed 2/3 of the volume of the test box, and the total weight of the materials should not exceed 35kg/m3).

3. Open the main power switch behind the machine when checking that the power connection is correct.

4, Turn on the POWER switch on the panel to start the controller display, and then operate on the controller, see the controller operation manual.

5. If you need to observe the condition of the test sample during the test, turn on the LIGHT switch, and do not open the door during the test.

Of course, in addition to the above important five points, the use of constant temperature and humidity test chamber also needs to pay attention to many other small details. Because when doing the test, under normal circumstances, the door is closed, so we can not see the working conditions inside the laboratory and the position and shape of the test sample, so we must pay attention to its position when placing the test sample.
