Description
The LY Series is Figurtech's most widely deployed direct pressure leak tester — a workhorse instrument for production lines that require fast, reliable airtightness validation on sealed assemblies, housings, and enclosures.
How It Works
The LY uses positive-pressure direct detection: the test cavity is pressurized, isolated, and held while an internal sensor measures pressure decay over a defined dwell time. A four-stage automatic cycle (Pressurize → Stabilize → Measure → Exhaust) delivers consistent, repeatable results without operator intervention. On-board temperature drift compensation maintains accuracy across shifts and ambient fluctuations.
