PQWT PQ125E Intelligent Pipeline Water Leak Detector

Professional Multi-Sensor Water Leak Detection System for Municipal, Industrial & Residential Pipelines

The PQWT PQ125E is the most advanced model in the PQ125 Series, combining multiple acoustic sensors with tracer gas leak detection technology to accurately locate underground water leaks in virtually any environment. Featuring AI-assisted waveform analysis, intelligent noise filtering, and a large 7-inch touchscreen display, the PQ125E is designed for professional leak detection across municipal water networks, industrial facilities, commercial buildings, and residential plumbing systems.

Unlike conventional leak detectors, the PQ125E allows technicians to adapt to different pipe materials, burial depths, and environments by selecting the most suitable sensor for the application.

Key Features

  • AI-assisted leak detection with intelligent waveform analysis
  • 7-inch high-resolution colour touchscreen
  • Multi-sensor platform for indoor, outdoor and tracer gas detection
  • Acoustic resonance and dual-membrane sensing technology
  • Advanced noise filtering for improved accuracy
  • Adjustable gain and volume settings
  • USB data transfer to computer
  • Lightweight portable design
  • Rechargeable 7000mAh lithium battery
  • Up to 8 hours operating time

Applications

Ideal for locating leaks in:

  • Municipal water distribution networks
  • Residential plumbing systems
  • Commercial buildings
  • Fire protection pipework
  • Industrial process water systems
  • Underground pipelines
  • Plastic and metal pipe installations

Sensor Configuration

The PQ125E includes five specialised sensors allowing detection in almost any scenario.

DMR-H40 Dual-Membrane Sensor

Designed for confined indoor environments where high contact sensitivity is required.

Suitable for:

  • Wall leaks
  • Floor leaks
  • Tight spaces
  • Pipe galleries

DMR-V59 Dual-Membrane Sensor

A lightweight portable sensor optimised for general indoor leak detection.

Suitable for:

  • Buildings
