High and low temperature testing machines can be divided into "alternating test" and "constant temperature test" according to the test method and industry standards. Both test methods are upgraded and expanded on the basis of high and low temperature test machines, and the alternating test box can be used once. The high temperature, low temperature and time required for sex will be set in the instrument parameters. The test box will follow the set procedure. The high and low temperature test machine is doing a fixed temperature, making the test effect closer to the natural climate and simulating the worse. The natural climate makes the tested samples more reliable.
Nowadays, high and low temperature testing machines have become a must-have device in the laboratory. However, how should we correctly choose a test equipment that suits us? The following small series for you to analyze the factors of the purchase of high and low temperature testing machine.
The volume of the product to be tested (W × D × H) shall not exceed 20 to 35% of the effective working space of the test chamber. It is recommended to use no more than 10% for products that generate heat during the test. Therefore, when purchasing a high and low temperature test machine, you need to know the size of the inner box you need.
The quality of the product is the most critical part. No matter the price is cheap, the quality of a piece of equipment is useless. When purchasing high and low temperature testing machines, we should choose some well-known domestic brands, and learn more about some environmental testing equipment industry information, so that we can better understand the reliability of some products. Let yourself buy the rest assured, use the comfort.
After-sales service is also a factor to consider. It is inevitable that the equipment will take a long time to malfunction. However, it is most critical to see how the reaction speed of the original manufacturer is faulty. Is it possible to solve the problem of equipment failure for you in time? And the technical quality of the original manufacturer's engineers is reliable, can you completely handle the failure of this high and low temperature test machine for you. This is a question we need to consider when purchasing.
When purchasing high and low temperature testing machines, we should not only consider the unilateral factors of price, but also many of them are worth considering. Therefore, Xiao Bian is here to warn everyone, can not just look at the price and blindly buy it! ! !
