Eight key points of choosing high and low temperature test chamber:
1.No matter whether it is selected for high and low temperature test chamber or other test equipment, it should meet the temperature conditions specified in the test requirements;
2.To ensure the uniformity of temperature in the test chamber, forced air circulation or non-forced air circulation mode can be selected according to the heat dissipation of samples;
3.The heating or cooling system of the high and low temperature test chamber shall have no effect on the samples；
4.The test chamber should be convenient for the relevant sample rack to place samples, and the sample rack will not change its mechanical properties due to high and low temperature changes;
5. High and low temperature test chamber should have protective measures. For example: there are observation window and lighting, power disconnection, over-temperature protection, various alarm devices;
6. Whether there is remote monitoring function according to customer requirements;
7. The test chamber must be equipped with automatic counter, indicator light and recording equipment, automatic shutdown and other instrument devices when carrying out the cyclic test, and it must have good recording and display functions;
8.According to the sample temperature, there are two measurement methods: upper wind and lower wind sensor temperature. The position and control mode of temperature and humidity control sensor in the high and low temperature test chamber can be selected according to the customer's product test requirements to select the appropriate equipment.
