Abstract
The utility model discloses a leak detector for welding tightness of a water blocking breathable film. The leak detector comprises a test board and a water injection pressure device. The test board comprises a sample stage which is communicated with the water injection pressure device. The leak detector also comprises a test electrode and a warning device. The test electrode is disposed right above the sample stage. Technical effect of the leak detector is that a sample is disposed on the sample stage and contacts the test electrode, and if the sample leaks, current is generated between the test electrode and the sample stage and the warning device alarms. If the sample does not leak, current is generated between the test electrode and the sample stage, and the warning device does not alarm, thereby achieving an objective that unqualified leaking samples are detected.
