Seal Tester

The sealing tester detects the sealing performance of packaging by applying pressure media, identifying leakage points through pressure decay or bubble observation methods. It is used for verifying the sealing integrity of food, pharmaceutical, and other packaging to ensure products do not leak during transportation and storage.
Selection
When selecting a leak tester, consider the material and dimensions of the test object to match the corresponding fixtures and pressure range. Focus on the instrument's accuracy and stability, and choose the appropriate testing method—positive pressure, negative pressure, or vacuum decay—based on the detection standards. Determine the level of automation according to the daily testing volume, and verify the ease of equipment calibration and maintenance.
