Food package negative pressure leak tester is based on ASTM D3078 bubble emission method and detects the gross leaks of flexible packaging with headspace gas. Leak tester is working by creating positive pressure inside pouch after vacuum is drawn away the pouch if force to plug small leaks.
Food package negative pressure leak tester has the following features:
1. Vacuum ejector betters than vacuum pump in creating a stable pressure
2. Digital vacuum degree and test time setting
3. Automatic vacuum maintenance and air back-flushing
4. Easy operation and maintenance
5. Transparent, thick and high quality PMMA chamber ensures observation and safety
6. Different chamber sizes available
