High-low temperature alternating test chamber In the high temperature test, if the temperature 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 very slowly, it is necessary to look at the air circulation system and see if the adjustment baffle of the air circulation is normal. Low temperature does not reach the test index Observed temperature changes, is the temperature drop is very slow, or the temperature rose to a certain value after the temperature has a tendency to rise, the former must check, do low temperature test before the studio drying, so that the work After the chamber is kept dry, the test sample is put into the work chamber and tested again. The test sample in the work chamber is placed too much, so that the wind in the work chamber cannot be fully circulated.
If it is not a similar situation, you can ask a professional manufacturer - special repair. In the heat and humidity test of high and low temperature alternating test chambers, the actual humidity will reach 10 or the actual humidity and 0% target humidity will differ greatly, and the value will be much lower. It may be caused by the drying of the gauze on the wet-bulb sensor. Check the wet-bulb sensor for water shortage. The water level in the water tank is automatically controlled by a water level controller. Check whether the water level controller water supply system is normal and whether the water level controller works normally. You can change a wet ball gauze or try again with purified water. Or ask a professional electrician to overhaul the circuit control system. In addition to the correct operation of the test personnel according to operating procedures, it should also understand its structure. The thermal shock tester consists of a box, an air circulation system, a refrigeration system, a heating system, and a humidity control system. Another cause of temperature shock test chamber failure may also be due to poor ambient temperature, manufacturers recommend the best temperature of 5-28 degrees (average temperature of 24 hours at 24 degrees), humidity can be about 95%, any precision instruments are Need to have a good place to plant to ensure that the instrument to play the best effect. Ensure the product's service life. This maintenance tips should be known to any laboratory manager or machine operator.
