Pressure Decay Leak Tester for HDPE Bottles

Automatic air pressure decay tester with cap-sealing head that detects leaks in empty HDPE bottles by monitoring loss of pressure. Used for in-line sampling and lab QC at bottle makers and fillers.

Specification

The bottle neck is sealed by a pneumatic head and filled with air at a few kPa, then isolated while a sensor tracks pressure drop over a few seconds. Any decay above the set limit marks the bottle as leaking. It gives fast, objective results without water.

Features

• Differential pressure sensor with 0.1 Pa resolution
• Pneumatic sealing head for different necks
• Programmable test pressure, fill and dwell times
• Pass/fail output with lights
• Stores master test recipes
