Are the high and low temperature test box and the high and low temperature alternating test box the same product? When choosing high and low temperature products, how to choose? The pre-sales engineer of Beijing Yashilin Test Equipment Co., Ltd. explained this issue as follows:
As a kind of temperature control test chamber, the high and low temperature test box and the high and low temperature alternating test box belong to the same concept in terms of the test meaning of the instrument: change and control the temperature change. Both high and low temperature test chambers and high and low temperature alternating test chambers are mainly used for high and low temperature reliability tests of industrial products. The components and materials of related products such as motorcycles, electronic and electrical engineering, universities, scientific research institutions, aerospace, marine weapons and other related products are tested under various high and low temperature (alternating) cycles.
The structural hardware facilities of the high and low temperature test chamber and the high and low temperature alternating test chamber are basically the same. The high and low temperature test chamber and the high and low temperature alternating test chamber are also similar in software, electrical control system, measurement and control system, circulation system and so on.
In the final analysis, the biggest difference between the two test equipments is the control part. The control part of the high and low temperature test chamber is an ordinary instrument, and the control part of the high and low temperature alternating test chamber is mainly through a programmable instrument. Ordinary instruments can only be used for fixed-value tests, and can be controlled by a single test in accordance with the setting requirements. The temperature change can only be operated manually. The programmable instrument is fully automatic control, you can set the parameters to be set and the number of tests in advance, and then work according to the set program.
The high and low temperature test chamber and the high and low temperature alternating test chamber are basically the same as the temperature control system due to the configuration of the refrigeration and dehumidification system. Therefore, the decisive reason for the price is mainly the instrument. Under the same performance conditions, the high and low temperature alternating test chamber Generally, it is slightly more expensive than the high and low temperature test chamber, and the cost difference is about six to eight thousand yuan.
