High and low temperature test chambers are widely used. It can be said that this equipment is used for testing except for the food industry. Such as: colleges and universities, research units, aerospace, electronic and electrical. The application to the electronics industry is extremely extensive. In this chapter we talk about the significance of high and low temperature test chambers for the mobile phone industry. There are so many mobile phone brands in the market in Shanghai. Each mobile phone has been tested in advance before leaving the factory. It is not a mobile phone that can be sold directly to users. The performance of the mobile phone must be tested before leaving the factory, such as whether the mobile phone can be waterproof, whether it can be dustproof, whether it can withstand the temperature in hot or cold areas, and whether it can be used or talked under harsh natural conditions. The high and low temperature test chamber is a simulated temperature environment with a temperature range of -20 -40 -60 -70 degrees Celsius and a high temperature of 150 degrees Celsius. Generally speaking, the mobile phone must be done at a low temperature of -40 degrees Celsius before leaving the factory. In the southern summer, the maximum temperature is about 35 degrees Celsius, and in winter, the lowest is about -2 °C. There is no problem with the mobile phone. If the lowest temperature in the northern winter reaches -40 degrees Celsius, can the phone be used normally? Therefore, it is necessary for the mobile phone to do the low temperature test. The high and low temperature test chambers have test lead holes for the products with live test (shown below), and the phone can be powered on during the test. All objects whose temperature is higher than absolute zero are constantly emitting infrared radiation energy into the surrounding space. The size of the infrared radiation energy of an object and its wavelength distribution are closely related to its surface temperature. Therefore, the surface temperature of the object can be accurately measured by measuring the infrared energy radiated by the object itself. This is the principle on which the infrared thermometer operates.

After the outbreak, measuring body temperature has become a convenient and intuitive way to find potentially infected people. Many regions require companies to prepare non-contact temperature measuring instruments when they resume work.
