Myth 1: Space Size

When purchasing a constant temperature and humidity test chamber, determine the size of the test chamber. The constant temperature and humidity test chamber is not filled with the working chamber like a refrigerator, and the samples placed in the box should be separated from the inner wall to ensure the air flow around the sample. In general, the ratio of the total volume of the sample to the total volume of the inner box should not exceed 1:3.

Myth 2: Understanding Terminology

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

Myth 3: The difference between communicative and non-alternative

The difference between alternating and non-alternating in the constant temperature and humidity test chamber is the controller used. The standard type is that the frame is not interchangeable in the constant temperature and humidity test chamber, the controller used is the digital display button, which can fix the temperature point. The controller used in the alternating constant temperature and humidity test chamber is a programmable controller, which can set the required temperature point and constant time on the controller at one time. The test box will be tested according to the set program without the need to manually set up the test device.
