Vacuum leak tester

The equipment carries out pre-vacuuming through a vacuum generator, uses a vacuum bar to further extract a high vacuum operation, and uses a high-precision vacuum sensor to carry out timely feedback detection of the vacuum degree in the cavity under the negative vacuum state of the product to be tested. The automatic control system evaluates the pressure leakage of the target product through the selected program and parameters, and determines whether the air tightness of the product is qualified.
