Accutrak VPE-GN (Gooseneck) Ultrasonic Leak Detector

Accutrak VPE-GN (Gooseneck) Ultrasonic Leak Detector

Description

• The VPE‑GN (Gooseneck) is a specialized ultrasonic leak detector featuring a flexible gooseneck configuration that enables accurate readings in hard‑to‑reach places.

• Uses heterodyning technology to convert ultrasound (36 kHz – 42 kHz) into an audible 0 Hz to 4 kHz output while preserving original sound characteristics, allowing users to distinguish leaks from mechanical or background noise.

• Provides visual output via a 10‑element bar graph for quick, intuitive indication of ultrasound presence and relative strength.

• Features adjustable sensitivity with a continuously variable slide control, allowing operators to locate leaks from a distance and then precisely pinpoint the exact location.

• Detects a 5 psi leak from a 0.005″ hole at 20–30 feet (depending on background noise).

• Capable of detecting leaks equivalent to 1.5 oz/year of refrigerant.

• Works equally well for compressed air, nitrogen, and any gas that generates ultrasonic sound during flow, including vacuum leaks.

• Resists interference from wind or high concentrations of leaked gas/refrigerant.

• Housed in a durable blue ABS body with a Velvet Lexan back‑printed top label.
