Usually the conventional high and low temperature test chamber is heated 3 degrees per minute, and the temperature is reduced by 1 degree per minute. However, the cold and hot shock test chamber quickly completes the conversion from high temperature to normal temperature or normal temperature to low temperature within 5 minutes, so as to achieve the product The more brutal test. The price of the high and low temperature test box and the cold and hot shock test box are also different. Different performances and different prices. In comparison, the price of the cold and hot shock test box is relatively higher. And their appearance is different. In addition, the thermal shock test box is also divided into three box type and two box type, three box type and two box type are also different. Users need to be aware of what they need when buying a device before they can buy a device that suits them.
