[0002] At present, the method of testing the effectiveness of thermometers is relatively simple. There is no batch testing device. With a single testing device, the replacement of test pieces is relatively common. The long-term disassembly of the connecting nuts is prone to thread slippage. The damage of the thread affects the sealing effect and also causes damage to the thread mouth of the test piece.
[0003] The existing device is relatively simple and requires clamping of each piece, which is time-consuming and laborious. The device designed now is equipped with a quick connector, which is more convenient to clamp and more efficient. More than a dozen temperature gauges to be tested can be quickly installed at one time, and the values of the tested temperature gauges can be checked at the same time. The numerical accuracy deviation of the test gauges of the same batch in the same time period is more obvious. Utility Model Content
