Three misunderstandings to avoid when buying a constant temperature and humidity test chamber

Constant temperature and humidity test chamber, constant temperature machine, constant temperature and humidity chamber, etc., are commonly used to test the performance of materials in different environments and the heat resistance, cold resistance, dryness and humidity resistance of different materials under the test. So, what misunderstandings should be avoided when buying a constant temperature and humidity test chamber?

The first misunderstanding is that when buying a constant temperature and humidity test chamber, you must first determine the size of the test chamber. The constant temperature and humidity test chamber does not need to fill the entire space like a refrigerator. The sample placed in the test chamber should be separated from the inner wall to ensure air circulation around the sample. The ratio of the total volume of the sample to the total volume of the inner chamber should not exceed 1:3.

The second misunderstanding is to understand the terminology to understand the meaning of terms related to the constant temperature and humidity test frame. For example: temperature set point, temperature stability, temperature fluctuation, temperature uniformity, temperature change rate (humidity temperature rate), humidity deviation, etc.

The third misunderstanding is the difference between alternating and non-alternating. The difference between alternating and non-alternating in a constant temperature and humidity test chamber is that the standard type is a constant temperature and humidity test chamber, which is not interchangeable. The controller used is a digital display button type. Fixed temperature point.
