What non-standard constant temperature and humidity cycling chamber, it is based on a standard temperature and humidity cycling chamber and derived from the term. There are only two types of non-standard equipment in the environmental testing equipment industry.

1, from the appearance of the volume points: common standard constant temperature and humidity cycle chamber volume of the internal volume of 80L, 150L, ​​225L, 408L, 800L, 1000L, 1300L and other standard volumes, non-standard constant temperature and humidity cycle test box to be based on Customer specific design.

2, from the equipment parameters to be divided: common standard constant temperature and humidity cycle test chamber temperature range A: -20 °C ~ 150 °C B: -40 °C ~ 150 ° CC: -60 °C ~ 150 ° CD: -80 °C ~150°C, and humidity range is 20~98%. Non-standard should be designed according to the specific situation of the customer.

Second, based on the above specifications, if there is not a similar size or temperature range, or other humidity range, it belongs to non-standard constant temperature and humidity cycle test chamber. At present, the scope of use of non-standard constant temperature and humidity cycle test chamber is relatively small, the main reasons are as follows:

1, the temperature range from -80 °C, to high temperature 150 °C, can meet both domestic and domestic double standards;

  

2. Many types of domestic constant temperature and humidity cycle test chambers can meet the needs of customers

3, non-standard constant temperature and humidity cycle test chamber is relatively expensive, from the economic point of view, the customer chooses less. Of course, there are some customers, because the test products are very special, must be customized according to non-standard, there are a few cases, the general non-standard customized constant temperature and humidity cycle test chamber, can achieve tailor-made features, in the test process, very consistent Test requirements.
