Buying high and low temperature test chambers is also a matter of learning. From technical indicators to buying brands, I don’t know if I have a lot of doorways. So, it’s better to find some problems first and then buy them.

Technically something to watch out for
1. Select the high and low temperature test chamber to understand the "number of horses"
When purchasing high and low temperature test chambers, many people know that there is a word like "number of horses", which is probably the power consumption of a compressor, 1 horse = 1 horsepower = 735W. The horse is not the same as the cooling capacity. What is the number of high and low temperature test chamber compressors that are usually mentioned, and the compressor cooling capacity is estimated based on the power consumption of the compressor. This is the number of compressors in terms of refrigeration.
2. Select high and low temperature test chamber to understand "alternative"
When people buy high and low temperature test chambers, the salesperson will confirm with you whether or not there is an alternating function. Alternation means that the high and low temperature test chamber can be used for high temperature and low temperature cycle test and has automatic calculation function. It supports real-time computer monitoring, historical curve playback, program editing, remote diagnosis, FTP upload and download, and historical fault viewing.
3. Select high and low temperature test chamber to understand "professional terminology"
Work space: The part of the high and low temperature test box that can maintain the specified conditions within the specified tolerance range.
Temperature set point: The desired temperature set by the test chamber control unit.
Actual temperature: The temperature at any point in the working space of the test chamber after stabilization.
Temperature stability: The temperature at all points in the workspace reaches the temperature set point and the dimension continues to within a given tolerance.
Temperature Fluctuation: The difference between the higher and lower temperatures at any point in the workspace at any given time interval after stabilization.
Temperature uniformity: The greater the difference between the temperature averages of any two points in the workspace at any time interval after stabilization.
Temperature Change Rate: The rate of transition between two given temperatures measured at the center of the workspace, in °C/min.
Temperature deviation of the workspace: The difference between the average of the center temperature of the workspace and the average of the temperatures of other points in the workspace at any time interval after stabilization.
Limit temperature: The higher and lower measured temperatures achieved in the workspace after stabilization.
