High and Low Temperature Damp Heat Alternating Test ChamberSuitable for aerospace units, its maintenance difficulty is one of the highest among environmental testing equipment. Today, the editor summarized some common faults and troubleshooting methods of temperature shock test chambers:

　　1.High and Low Temperature Damp Heat Alternating Test ChamberIn high-temperature testing, if the temperature change does not reach the test temperature value, the electrical system can be checked and the faults can be eliminated one by one. If the temperature rises slowly, you need to check the air circulation system to see if the regulating baffle of the air circulation is open normally.

2. If the low temperature does not meet the indicators of the experiment, observe the temperature changes, whether the temperature drops slowly or there is a tendency for the temperature to rise after reaching a certain value. The former should be checked to see if the working chamber is dried before conducting the low temperature test. After keeping the working chamber dry, put the test samples into the working chamber and conduct the experiment again. Check if there are too many test samples placed in the working chamber, which prevents the air in the working chamber from circulating sufficiently. If it's not a similar situation, you can ask the supplier for maintenance. Test personnel should not only operate correctly according to the operating procedures, but also have an understanding of its structure. The cold and hot shock testing machine consists of a box, an air circulation system, a refrigeration system, a heating system, and a humidity control system.

3. Additionally causingHigh and Low Temperature Damp Heat Alternating Test ChamberThe cause of the malfunction may also be poor environmental temperature. It is recommended that Jia maintain a temperature of 5-28 degrees Celsius (with an average temperature of around 24 degrees Celsius over 24 hours) and a humidity of around 95%. Any precision instrument needs to be placed in a good factory location to ensure that it performs well. Ensure the service life of the product.

The above three maintenance tips should be known by any laboratory manager or machine operator.
