Introduction
The GB-M2 sealing tester uses compressed air as the power source and high-precision electronic pressure sensor as the measurement method. Through microcomputer control, it can effectively compare and evaluate the sealing process and sealing performance of flexible packages, and provide scientific information for determining relevant technical requirements. basis. It is suitable for sealing performance test of flexible packages in food, pharmaceutical, daily chemical and other industries.
Test principle
By evacuating the vacuum chamber, the sample immersed in water will generate a pressure difference between the inside and outside, and observe the gas escape or water infiltration in the sample, so as to judge the sealing performance of the sample.

Features
High-quality accessories, quality assurance
The built-in high-precision pressure sensor has high sensitivity and can monitor the intake pressure in real time.
Fully automatic operating system
Set the vacuum degree and holding time as needed, the instrument is fully automatic for testing, automatic vacuuming, holding the set time, automatic stop and inflation return.
The new air circuit system uses compressed air and is pneumatically driven, which can realize quick inflation and return to the position, and the internal and external air pressures are consistent.
Excellent appearance and convenient operation
The host is embedded with a 7-inch high-resolution color LCD screen, with clear views, sensitive touch controls, and easy operation.
The instrument has its own operating system, which can be tested independently from the computer, and the data can be processed automatically.
