When the high and low temperature test chamber is in operation, the test piece needs to be tested at high and low temperature. Therefore, the test piece needs to undergo high and low temperature test aging and high and low temperature test cycle system testing to obtain relevant results. During this process, temperatures such as high and low temperature may occur and take a long time to stabilize. Is there any way to quickly stabilize the temperature of the high and low temperature test chamber equipment?
The temperature of the high and low temperature test chamber has a certain tolerance, which is generally between two and three degrees Celsius. This is determined by fully considering the slow temperature change, the absolute measurement error, and the high and low temperature test chamber the temperature change in the equipment space. If it is to maintain the relative humidity of the equipment within the specified tolerance, it is necessary to have a temperature difference between any two points in the equipment at any time in a relatively small range. If the temperature difference of the equipment is larger than 1k, the humidity conditions of the high and low temperature test chamber equipment will not meet the standard. Therefore, in order to maintain the set humidity, the temperature fluctuation in a short period of time should be kept at degrees 0.5 and the test piece temperature should be kept between three degrees.
① After the test piece is placed in the high and low temperature test chamber, the temperature of the high and low temperature test chamber equipment must be adjusted to 25 ℃ to maintain this state until the test piece reaches the temperature and is stable.
② Before placing the test piece in the high and low temperature test chamber, the test sample shall be placed in another box first, and the follow-up work shall be carried out after the temperature is stable. No matter which method is used to stabilize the temperature, the relative humidity of the equipment must be within the specified standard limit. After the test piece temperature is stable in the box, the relative humidity in the equipment box of the high and low temperature test box should be greater than 95%, and the equipment environment temperature should be Twenty-five degrees.
The above is about stabilizing the temperature of the high and low temperature test chamber. If you want the temperature of the equipment to start to stabilize, you can use these methods.
