KEY FEATURES & BENEFITS
HIGH‑PRECISION SOUND ISOLATION: Four adjustable frequency bands (200 Hz – 3 kHz) allow you to filter out background noise and focus on specific sound signatures (e.g., bearing wear, valve ticks, airflow, electrical arcing).
EXTREME AMPLIFICATION: 0‑100 dB adjustable gain makes even the faintest mechanical or acoustic signals clearly audible.
MULTIPLE SPECIALIZED SENSORS: Includes:
External (Outdoor) Sensor: For general external engine or machinery inspection.
Large & Small Indoor Sensors: For confined spaces, panels, or different surface areas.
Handle Grip: For comfortable, extended use.
COMPLETE PORTABLE KIT: Comes in a protective aluminum alloy case with all components, a charger, and headphones for private listening.
LONG BATTERY LIFE: Over 30 hours of operation on a single charge for extended fieldwork.
VERSATILE DIAGNOSTIC TOOL: Ideal for automotive repair, industrial maintenance, HVAC system checks, leak detection, and electromechanical troubleshooting.
TYPICAL APPLICATIONS
Automotive: Diagnosing engine knocks, timing chain noise, bearing wear, transmission issues, exhaust leaks.
Industrial: Pinpointing bearing faults in motors, pumps, and gearboxes; detecting valve leaks or airflow irregularities.
HVAC: Identifying compressor problems, refrigerant leaks, or blower wheel imbalances.
General Maintenance: Locating electrical arcs, loose components, or abnormal vibrations in machinery.
