Positive pressure seal tester and negative pressureSeal detector, the materials tested by these two detectors are different due to different methods and pressures.

Also different. 

1, negative pressure seal detector

Negative pressure sealing use: suitable for sealing testing of electrical appliances, etc., negative pressure sealing detection

The instrument is designed and manufactured in accordance with the relevant provisions of the sealing performance test method for flexible packages.Experiments can effectively compare

and evaluate the sealing process and sealing performance of flexible packages to provide a scientific basis for determining relevant technical requirements.Also possible

Carry out the sealing test of the specimen after the drop and pressure test.

Principle of negative pressure sealing test: By evacuating the vacuum chamber, the sample immersed in water will generate a pressure difference between the inside and outside, and the test will be observed.

The gas escape situation in the sample is used to determine the sealing performance of the sample: or the vacuum chamber is evacuated to generate internal and external pressure on the sample.

Observe the sample expansion and shape recovery after releasing the vacuum to determine the sealing performance of the sample.

2, Positive pressure seal tester

Uses of positive pressure sealing: waterproof testing of electronic products, air tightness testing of automobile parts, the positive pressure seal tester can pass the test

Effectively compare and evaluate the tightness of bottle caps or closed containersSealing technology and sealing performance provide a scientific basis for determining technical requirements.

The principle of positive pressure sealing is to use a compressed air source to control the pressure and time through a microcomputer to detect and inspect

The sealing performance and processing technology of the bottle cap.This instrument provides an advanced, practical and direct method for the quality and reliability of sealed packaging.

Visual and effective test method, simple operation, unique and novel instrument appearance design, easy to observe experimental results, using unique

technology, cleverly cutting out part of the sealing part for testing, which not only avoids explosions, but also improves the existing instruments on the market.

The accuracy has been improved by as much as ten times, filling a gap in the country. You can also use two stations to test two samples at one time, achieving a

The machine has multiple effects.Because there are no explosion defects, testers can observe the leakage at close range through the transparent observation window.
