Please keep in mind the "Five Don'ts" principle when using the high and low temperature test chamber

Keep away from heat sources

When placing the high and low temperature test box, generally 60~70cm of use and maintenance space should be reserved on both sides, which can help the high and low temperature test box to dissipate heat. Also be careful not to put it together with some heating appliances, so as not to increase the power consumption of the high and low temperature test box

Second, the opening time of the high and low temperature test box should be short. In case of power failure, do not rush to open the door of the high and low temperature test box.

Third, the environmental temperature difference should not be too large

The temperature difference in the operating environment is too large, which will cause a large amount of water vapor in the high and low temperature test box. Over time, it will accelerate the corrosion of components, which can easily cause damage to the high and low temperature test chamber.

Fourth, do not stop using the high and low temperature test chamber

In order to save electricity, many customers will put the high and low temperature test box in a "hibernation" state if they are temporarily unused. In fact, it is unscientific to do so, and it is likely to affect the service life of the high and low temperature test box. The evaporator of the test box is mostly made of aluminum. Organic matter on the aluminum wall will become moldy and deteriorate, corrode the aluminum plate, and damage the refrigeration system after it is disabled. The plastic of the inner tank is easier to age at room temperature than at low temperature. Therefore, it is best not to let high and low temperatures. "Shutdown" of the test chamber. If the high and low temperature test chamber must be stopped, it must be defrosted and cleaned, and placed in a ventilated and dry place, away from direct sunlight. *Good to power on the high and low temperature test chamber once a month, let the compressor run normally for half an hour to one hour before turning off.

Fifth, do not switch frequently

In winter, the general office temperature is around 0-20℃, and the working temperature of the high and low temperature test chamber is relatively high. If it is frequently switched on and off, its internal components may be destroyed during the transition between high and low temperatures.
