How to choose high-quality and economical high and low temperature test chambers? What problems should you pay attention to? I believe this is the concern of every purchaser and user! According to Xiaobian's rich experience in the ring test industry for many years, he summarized five points.诀窍:

First point: temperature range

Determine the maximum temperature range that can be used in high and low temperature test chamber tests. For example, if you have long-term low temperature of -45 °C and high temperature of 120 °C, then you should choose a temperature range of -60 °C-150 during the selection process. °C equipment. The limit temperature of the equipment cannot be selected. If the equipment is fully loaded, the life will be reduced, and the remaining 10% should be the best.

Second point: humidity range

Generally speaking, the standard stipulates that the humidity range of the high and low temperature test chamber is 30%-98%RH, and the humidity range of the large part of the manufacturer is 20%-98%RH. If there is a requirement for lower humidity, it needs to be explained to the manufacturer.

The third point: the workspace

Determine the maximum high and low temperature test chamber studio space that you can use. Generally, one-third of the studio space is best, and no more than two-thirds. Also note that when the product is placed, it should not accumulate too high to block the air duct, nor can it be against the wall, which will affect the uniformity inside the box.

Fourth point: control instrument

High and low temperature test chamber control instruments are generally available in both digital display and programmable. Digital display can only be a single group test. If you have the requirement of cycling multiple sets of tests, you are advised to choose a programmable meter. It is more worry-free during use, so you should always pay attention to the end of the test.

Fifth point: bearing

The load-bearing capacity of the high-low temperature test chamber sample holder is 30KG/layer, and the overall load capacity of the working space is about 50-60KG. If the sample to be tested is very heavy, it needs to be explained to the manufacturer, and the manufacturer does the reinforcement treatment. Manufacturers with more than 200KG will make structural changes, such as horizontal, to facilitate product placement.

Xiaobian simply lists the most important items. Buyers and users should consider at least the above five points to purchase high and low temperature test chambers, and also the temperature rise and fall rate, external water supply device, test hole, door width, test report, etc. considerate
