How to make the temperature of the high and low temperature test chamber quickly enter a stable state?

First of all, do you know what the purpose of the high and low temperature test chamber is? Upon receiving approval from the superiors for the procurement of high and low temperature test chambers, you will need to understand some of its performance parameters and uses. In order to reasonably choose the ideal instrument. The following is a small series of Haotian equipment to analyze some of its main uses and performance parameters for you to choose.

The high and low temperature test chamber is an instrument for high temperature and low temperature test. Put the product into the test box, set the high temperature and low temperature conditions to be tested and the number of high and low temperature cycles to test the product. After the product has passed the high and low temperature aging and high and low temperature cycle test, evaluate the performance change of the high and low temperature test chamber. And reliability.

When the high and low temperature test chambers are returned to the test, it may be difficult to stabilize the high temperature and low temperature, or it may take a long time to stabilize. What should I do? Is there any way to make the temperature of the high and low temperature test chambers fast and constant? . The total temperature tolerance of the high and low temperature test chambers of 2 ° C or 3 ° C is determined by taking into account the absolute error of the measurement, the slow temperature change and the temperature change in the workspace, but in order to maintain the relative humidity within the specified tolerance range, The temperature difference between any two points in the working space must be maintained within a small range at any time. If the temperature difference exceeds 1K, the humidity condition will not meet the requirements. In order to maintain the specified humidity, the temperature should be maintained for a short period of time. At 0.5 ° C, the temperature of the test sample should be stable between 3 ° C, and stabilized by the following method: 1. After putting the test sample into the high and low temperature test box, adjust the temperature of the box to 25 ° C and keep until the test sample reaches The temperature is stable; 2. Before placing the test sample in the high and low temperature test chamber, place the high and low temperature box sample in another box; Dear customers, the above two methods for making the high and low temperature test box fast and stable Which one is used, the temperature stabilization time is reached, and the relative humidity must be within the limits of the specified standard atmospheric conditions for the test. The sample is in the high and low temperature circulation tank. After stabilization, the relative humidity inside the tank should rise to not less than 95% and the ambient temperature is 25 °C.
