Test device

Abstract

The application relates to a testing device. The testing device comprises a gas heater, a testing pipe, a temperature sensor and a control mechanism. The testing pipe is in communication with a gas outlet end of the gas heater. The testing pipe is configured to be connected to a heating mechanism to be tested. The temperature sensor is installed on the testing pipe and used to acquire the surface temperature of the testing pipe. The control mechanism is in signal connection with the temperature sensor and configured to be in signal connection with the heating mechanism to be tested. The control mechanism is used to test the heating performance of the heating mechanism to be tested. Thus, the heating mechanism to be tested can be directly installed on the testing pipe, the testing process is simplified, the testing time is saved, and the testing efficiency is improved.
