Non-standard touch type constant temperature and humidity testing machine is a term derived from the standard touch type constant temperature and humidity testing machine. There are only two types of non-standard equipment in the environmental testing equipment industry.
1, from the appearance of volume points: common standard touch-type constant temperature and humidity testing machine for the internal volume of 80L, 150L, ​​225L, 408L, 800L, 1000L, 1300L and other standard volume, non-standard touch-type constant temperature and humidity The test machine is designed according to the customer's specific conditions.
2, from the equipment parameters to points: common standard touch type constant temperature and humidity testing machine 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-standards should be designed according to customer's specific conditions.
Second, based on these specifications, if there is not a similar size or temperature range, or other humidity range, it belongs to non-standard touch-type constant temperature and humidity testing machine. At present, the use of non-standard touch-type constant temperature and humidity testing machine 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. There are numerous models of domestic touch-type constant temperature and humidity testing machines to meet the needs of customers.
3, non-standard touch-type constant temperature and humidity testing machine 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, they must be customized according to non-standard, there are a few cases, the general non-standard customized touch-type constant temperature and humidity testing machine, can achieve tailor-made features, in the testing process, Very much in line with the test requirements.
