Tool for testing in high and low temperature environments

The utility model relates to a tool for testing in high and low temperature environments. The device mainly comprises a direct-current power supply, a power supply switching device, a signal switching device, a display screen and the like. The direct-current power supply is connected to the power supply switching device, and can be conducted to a specific product to be tested at the same time through a button on the device. After the to-be-tested product is electrified, the signal output of the to-be-tested product reaches the signal switching device, and the test result of the product can be seen on the display screen through the switching button. 本实用新型专利是一种用于高低温环境测试的工装。主要包括直流电源、电源切换装置、信号切换装置、显示屏等。直流电源接入电源切换装置，通过装置上的按钮，可以在同一时间传导给特定的待测产品。待测产品通电后，其信号输出到达信号切换装置，通过切换按钮，可以在显示屏幕上看到产品测试结果。
