Negative pressure Leak Tester

Leak Tester is a kind of tester that use compression air to produce negative pressure by vacuum device to test the seal capability and processing technique of soft plastic packaging material in food and pharmaceutical industry. It also can test the specimen which has done the drop and compression test.

Product Details

Standards

GB/T15171-94 (the Seal Testing Method for soft packaging).

ASTM D 3078 Standard Test Method for Determination of Leaks in Flexible Packaging

Working principle:

To vacuum the vacuum room and make the pressure difference between inside and outside of the specimen in the water. We can evaluate the seal capability by observing the air permeability situation of the specimen.

Feature

1. The shell is made of high quality stainless steel

2. Air seal parts, automatic control components, vacuum control meter, timing controller, are imported

3. Vacuum pump automatically disconnected, automatic pressure compensation, set time prompts automatically, the vacuum set value can be maintain for a long time

4. Automatic digital display, reach the set pressure, stop, without any manual operation, pressure compensation, timing, blowback, automatically

5. With power security precautions.
