Product Information

The TS-LT3 Sealing Tester uses compressed air as its power source and a high-precision electronic pressure sensor as its measuring method. Controlled by an integrated microcomputer, the instrument enables effective comparison and evaluation of the sealing process and sealing performance of flexible packaging, providing scientific data to support the determination of relevant technical requirements. It is suitable for sealing performance testing of flexible packaging used in the food, pharmaceutical, daily chemical, and other industries.

Key Features

High-quality components for reliable performance

The built-in high-precision pressure sensor offers high sensitivity and enables real-time monitoring of intake pressure.

Fully automatic operating system

The vacuum degree and holding time are set as required, after which the instrument performs the full test cycle automatically — vacuuming, holding for the set time, stopping, and inflation return.

The pneumatically driven air circuit uses compressed air to achieve rapid inflation and return, keeping internal and external air pressures consistent.

Refined appearance with convenient operation

A 7-inch high-resolution color LCD screen is embedded in the housing, offering clear visibility and responsive touch control for easy operation.

The instrument runs on its own operating system, allowing it to test independently of a computer while processing data automatically.
