How to choose a constant temperature and humidity test chamber? Precautions for purchasing a constant temperature and humidity test chamber

If you are afraid of being deceived when purchasing a constant temperature and humidity test chamber, please read this article carefully and explain the precautions to be taken when purchasing a constant temperature and humidity test chamber, as well as how to choose a constant temperature and humidity test chamber?

1. Selection of size for constant temperature and humidity test chamber: Measure the size and volume of the test product. The size of the test chamber directly determines its size.

The temperature and humidity range of the test chamber is determined by the actual range of use of the product.

3. The size of the elevator and corridor door of the constant temperature and humidity test chamber will limit the size of the constant temperature and humidity test chamber.

4. Selection of constant temperature test box power supply: 220V single-phase power supply is generally used for test boxes below 150L; The 380V three-phase power supply is used for test boxes above 150L, which is reasonable and stable for the entire laboratory's electricity consumption, and is beneficial for the equipment's own service life;

5. Choose air cooling and water cooling: A small constant temperature and humidity test chamber within 1m3 is air-cooled, while water cooling is usually used for large temperature and humidity test chambers or rapid temperature change test chambers. Due to the large refrigeration configuration, the cold and hot shock test chamber is usually water-cooled.

6. Selection of compressor for constant temperature and humidity test chamber: The quality of the compressor determines the cooling effect of the test chamber. When purchasing, it is important to pay attention to the compressor brand used by the manufacturer.

Only by understanding the constant temperature and humidity test chamber can one choose a suitable constant temperature and humidity test chamber, which will give them more confidence when purchasing equipment.
