Fisher XLT30-D Acoustic Leak Detector with Multi-Sensor & Cylinder Probe

Fisher XLT30-D Multi-Sensor Acoustic Leak Detection System

The Fisher XLT30-D with Multi-Sensor is a professional acoustical leak detector engineered for locating underground water leaks on hard surfaces and turf. Combining ultra-sensitive microphones with non-distortion amplification, it delivers clear acoustic response for accurate leak pinpointing.

Advanced Frequency Filtering & Audio Control

• Operating frequency: 60 Hz–6 kHz (Gain 95 dB); 20–60 Hz (Gain >90 dB)
• All Pass, High Pass, Low Pass, Band Pass, and Notch filter modes
• Adjustable filter ranges from 150 Hz to 2.4 kHz
• LCD bar graph with 2-digit numerical readout
• 64-ohm high-performance headphones output

Multi-Surface Leak Detection Architecture

The Multi-Sensor supports both ground microphone and direct contact applications. It detects vibrations through concrete, asphalt, tile, and turf while minimizing external noise. The notch filter isolates interference from motors or traffic, enhancing leak signal clarity in urban environments.

Designed for Underground Water Infrastructure Work

• Municipal water line leak detection
• Commercial and residential underground pipe inspection
• Direct pipe contact testing using cylinder probe and sound rods
