Three major misunderstandings in the purchase of constant temperature and humidity test chambers

Date: Nov 03,2020 Views: 398

In the process of purchasing a constant temperature and humidity test chamber, users often have "take it for granted" because the user does not understand the technical issues of the constant temperature and humidity test chamber.

 

Here, we explain some misunderstandings that often occur, and hope that users can easily buy a good constant temperature and humidity test chamber for themselves when buying a constant temperature and humidity test chamber.

 

Misunderstanding 1: Space size When purchasing a constant temperature and humidity test chamber, first determine the size of the test chamber. The constant temperature and humidity test chamber does not fill the studio 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 should not exceed 1:3. To

 

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

 

Misunderstanding 3: The difference between alternating and non-alternating The difference between alternating and non-alternating constant temperature and humidity test chamber is that the controller used is different, the standard type is constant temperature and humidity test chamber, the chamber is not interchangeable, and the control used The device is a digital display button type, which can fix the temperature point.

 

The controller used in the alternating constant temperature and humidity test chamber is an intelligent programmable controller. The required temperature point and constant time can be set on the controller at one time, and the test chamber will follow the set procedure. It can be tested without manual setting.
