Auto Noise Detector Kit with Acoustic Sensor, Extension Cables, and Headphones

Brief Overview

This is a purpose-built diagnostic tool for identifying and locating noise sources in automotive systems. The handheld detector unit pairs with a sensitive acoustic sensor and an extended cable system to reach problem areas without lifting entire vehicle components. If you're also stocking diagnostic equipment, consider pairing this with an acoustic amplification stethoscope for complementary diagnostic capabilities across your service offerings.

Key Features

• Portable Control Unit: Compact 26 × 21 × 10 cm handheld detector with three-knob interface (Light, Sound, Channel controls) and integrated speaker grille
• Extended Sensor Reach: Six sensor extension cables included (three 3-meter cables, three 5-meter cables) allowing mechanics to isolate noise sources from multiple points without repositioning vehicle
• Copper Clamp Probes: Eight alligator clamp probes with insulated sleeves and individual lead wires for secure, repeatable contact points on engine components, transmission housings, and suspension parts
• Over-Ear Headphones: 1.2-meter cable with 3.5 mm jack connector; padded design supports extended diagnostic sessions
• Acoustic Range: Sensor frequency response 50–20,000 Hz captures vibration across engine knock, bearing wear, loose fasteners, and exhaust system resonance
• Battery Powered: Four AA alkaline batteries (preferred) provide field independence; no shop power required
• Protected Transport: Semi-rigid zippered carrying case with molded compartments keeps all components organized and protected

Business Advantages for Resellers

High Diagnostic Value: Noise diagnosis is a recurring profit center in any service shop. Mechanics who can efficiently locate vibration sources sell more warranty work, extended diagnostics, and premium repair packages.

Complete Kit Positioning: Unlike single-probe stethoscopes, this multi-cable system with clamp probes gives customers a comprehensive noise-finding solution. Position it as the upgrade for shops moving beyond basic listening diagnostics.

Durable Multi-Use: The clamp probes, cables, and control unit are built for repeated use across dozens of vehicles. No consumable wear—single sale yields long-term shop utility.

Margin-Friendly: Diagnostic tools command healthy markups in professional channels. Price this as a specialized instrument, not a commodity accessory.

Application Guidance

• Engine Knock & Detonation: Position clamps on engine block to distinguish pre-ignition from mechanical noise
• Bearing Wear: Mount probes on transmission pan, differential housing, or wheel bearing areas to isolate failing bearings
• Loose Components: Trace vibration through exhaust hangers, heat shields, and suspension brackets
• Resonance Issues: Identify which subsystem (drivetrain, cooling, electrical) is generating customer-reported rattles

Volume Control Warning: The kit includes over-ear headphones to isolate ambient shop noise. Always instruct users to adjust volume gradually to safe listening levels, especially during extended diagnostic sessions.

Reseller Value Statement

This is a professional-grade noise diagnostic system, not a consumer gadget. It provides shops with a systematic approach to vibration troubleshooting, reducing guesswork and supporting upsell opportunities on diagnostics and repair confidence. Stock it as a specialized tool for service bays that want to differentiate themselves through precision diagnostics and faster repair turnaround.
