Several points to avoid when buying a constant temperature and humidity test chamber

1. When purchasing a constant temperature and humidity test chamber, first determine the size of the test chamber. The constant temperature and humidity test room does not fill the room like a refrigerator. The sample placed in the 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 shall not exceed 1:3.

2. Understand the meaning of terms related to the constant temperature and humidity test chamber. For example: set temperature, temperature stability, temperature fluctuation, temperature uniformity, temperature change rate (humidity temperature), humidity deviation, etc.

3. Understand the difference between alternating and non-alternating. The difference between alternating and non-alternating in the constant temperature and humidity test chamber is that the controller used is different, that is, the standard type of the constant temperature and humidity test chamber cannot be interchanged, and the controller used is a digital display button type, which can change the temperature Point fixed.
