Air tightness detection equipment is a waterproof air tightness detector using compressed air as the test medium. Its main purpose is waterproof detection, sealing detection, air tightness detection and leakage detection.The difference between the multi-channel air tightness detector and the multi-channel air tightness detector is that the air tightness detection of a product is only carried out once, and the multi-channel air tightness detection equipment can be tested for a number of products at a time, and the relative efficiency has been greatly improved.
