1.High and low temperature shock chamber Refrigeration conditions: 1. Compressor: The principle is the same as that of an air compressor. Located at the bottom of the equipment is the black guy with a round head and a round brain. 2. Condenser: It can be understood as a hot water heater or a still...
1.High and low temperature shock chamber All functions are controlled by computer, which is self-developed software, and has a good operation interface, which makes the user's operation and monitoring more simple and intuitive. The hold function can keep the program you are running in the current state....
Electronic products have a wide range of applications. The atmospheric environmental conditions during storage, transportation, and work are complex and changeable. In addition to the natural environment, factors affecting products include climate, machinery, radiation, biological and personnel conditions. The...
1. First open the high and low temperature alternating test chamber to make the equipment in the standby state; select one of the test methods according to the operating mode of the sample test requirements. Now the test is GB2423.4 high and low temperature alternating test, so it is best to have related test...
When testing temperature and humidity in industrial production, three comprehensive test chambers are often used. The three comprehensive test chamberintegrates the functions of temperature, humidity, and vibration. It is suitable for aerospace products, information and electronic instruments, materials, electrical...
Sand and dust test standard (the characteristic number of IP bit is 6) 1. Sand and dust test chamber The amount of talcum powder in the box is 2.1 kg. The talc powder used must be sieved through a sieve, the nominal wire diameter of the sieve is 50 microns, and the nominal free distance...
The Sand and dust test chamber is mainly used to test the enclosure sealing performance of electronic products, and is mainly used for the IP5X specified in the enclosure protection level standard. And IP6X two-level test. Sand and dust test chamber structure 1. The whole box adopts an...
At present, the test equipment commonly used at home and abroad is the compound salt spray test chamber. The equipment is mainly composed of a composite salt spray test chamber (spray chamber), a salt solution storage tank, a salt solution level controller, a properly treated compressed air system, one or more...
1. When the thermal shock test chamber is not cooling, you can check the circuit first to see if the compressor is operating normally, and use measurement to test whether the circuit switch is stable. If the switch is unstable, it will also cause the compressor to not work properly, which will also lead to no...
Many people will be misled by the name of the constant temperature and humidity test chamber, thinking that the temperature and humidity of the constant temperature and humidity test chamber are constant and cannot be used for alternating tests, like the plant cultivation room. However, this is not the case. It...
When the temperature and humidity controller of the three-chamber constant temperature and humidity test chamber shows abnormal humidity, we need to check the constant temperature and humidity test chamber. The inspection items are as follows: 1. Whether the pipeline in the machine room is too...
When the temperature of the constant temperature and humidity test chamber does not reach the set value, pay attention to the change of temperature. 1. The temperature drops very slowly. Two aspects need to be checked. One aspect is whether the studio has been dried before the low...
