F620LV

COMPACT LEAK TESTERS FOR LARGE VOLUME COMPONENTS

The F620LV is a compact, high-performance leak tester designed for large internal volume components such as EV battery packs, tanks, and housings. It delivers fast, accurate results using differential pressure decay with advanced environmental compensation.

Differential Pressure Decay with DNC (Differential Noise Canceling) for stable, precise results
Optimized for large volume parts with high-flow valves and fast cycle times
Fully programmable with up to 128 test programs and advanced connectivity options (USB, RS232, Fieldbus)

TECHNOLOGY

DNC Technology

NEGATE BACKGROUND DISTURBANCES FROM LEAK READINGS

When leak testing a large, flexible component in a ‘noisy’ factory environment, use ATEQ’s new Differential Noise Canceling (DNC) leak testing technology to produce faster, more accurate leak readings that are not influenced by fluctuating background disturbances.

FACTORY DISTURBANCE

Temperature Variations

Opening Doors or Windows, Fans, HVAC Systems…

Pressure Variations

Time of Day, Weather, Sound Level…

Vibrations

Machine Movement, Wind, Forklifts, Music…

ATEQ’s DNC Function Provides a More Stable Leak Reading by Compensating for Background Disturbances so They Don’t Influence the Leak Sensor.
