A quick tester for a transmitter laboratory comprises a standard gas generation device, a two-position three-way electromagnetic valve, a first three-way pipe, a calibration box for a meter to be evaluated and a differential pressure sensor. A gas outlet of the standard gas generation device is connected with a gas inlet of the two-position three-way electromagnetic valve, a gas outlet of the two-position three-way electromagnetic valve and a gas inlet of the calibration box for the meter to be evaluated are connected with two end ports of the first three-way pipe respectively, and another end port of the first three-way pipe is connected with the differential pressure sensor. The quick tester can evaluate whether a transmitter works reliably and can be widely applied to various power experimental investigation institutes and laboratories of a power system and factories for producing sulfur hexafluoride leakage monitoring meters. Furthermore, the quick tester has the significance in guaranteeing operation safety of sulfur hexafluoride electric equipment, preventing environmental pollution and damage caused by leakage of sulfur hexafluoride high pressure switches and protecting life safety of maintainers.
