The programmable constant temperature and humidity test chamber is used to detect high and low temperature cycle resistance of various products and materials, high and low temperature alternating heat and humidity, constant temperature and humidity, damp heat aging test, etc. It is an electronic component, LED lighting, plastic plastic, computer zero. Reliability testing equipment that must be available for accessories, power batteries, etc.
If the programmable constant temperature and humidity test chamber is used for low temperature test, if it is operated below 0 °C, it should be avoided as much as possible. Because it is easy to cause the internal evaporator and other parts to be sealed when the temperature is low. Phenomenon, especially the lower the temperature, the more serious the situation. If it must be opened, the opening time should be shortened as much as possible.
When the small constant temperature and humidity test chamber completes the low temperature operation, be sure to set the temperature condition at 60 ° C for drying for about half an hour, otherwise the desktop constant temperature and humidity chamber will freeze.
The above problems may have neglected the completion of the test for drying. If the programmable constant temperature and humidity test chamber is set to a high temperature and constant temperature and there is still ice formation after drying, please contact the constant temperature and humidity box manufacturer-Dongguan Aisihao Testing Instrument Co., Ltd.
