AquaLeak 600 – Water leak detector

The Gastech AquaLeak 600 is the top-specification digital water leak detector in the Gastech AquaLeak series — a high-gain amplified acoustic instrument system comprising two matched yellow instrument units, a large-diameter bell geophone sensor with a spike T-bar handle, and professional over-ear HiFi headphones, all supplied in a rugged yellow foam-lined carry case. Each instrument unit features a large color TFT display and a five-button navigation panel. The high-sensitivity piezoelectric sensors combined with high-gain amplification electronics detect acoustic vibration signals transmitted through the ground from pressurized water escaping buried pipes — with the visual TFT display outputting a real-time noise level bar graph that increases as the operator approaches the leak source. High-efficiency digital filters eliminate unwanted ambient noise interference from traffic, pumps, and urban background sources without removing the leak-specific signal components. The dual-unit configuration supports both contact probe and bell geophone sensing modes simultaneously across the two units.

Two probe systems are available for different access and depth scenarios: the tip probe for direct contact on valves, hydrants, and pipe fittings for pre-location work, and the large-diameter bell probe positioned on the road surface or ground directly over the buried pipe for soil-transmitted geophone leak location at greater depths. The bell geophone places its weighted base directly on the ground surface, using the large-diameter contact face to maximize acoustic coupling with the ground above the pipe. The HiFi headphone capsules provide high-resolution audio output alongside the TFT visual readout, allowing the operator to use both hearing-based and display-based signal identification simultaneously. The digital filters and high-gain system make the AquaLeak 600 the preferred choice for difficult detection scenarios — weak signals, deep pipes, noisy urban environments, and plastic or PE pipe materials.

The Gastech AquaLeak 600 is deployed by water network operators, specialist leak detection contractors, and utility survey teams for precise acoustic location of leaks on buried pressurized water distribution mains — covering both outdoor road-surface geophone surveys and indoor floor or wall detection in domestic and commercial properties. Its dual-unit and dual-probe architecture covers the complete workflow from initial contact-point pre-location through to surface geophone leak point identification in a single instrument set.

Leader Infra supplies this top-specification dual-unit digital water leak detector for water network operators and specialist leak detection contractors — delivering high-gain amplified geophone and contact probe detection with TFT display output, HiFi headphone monitoring, and digital filtering across all pipe materials and depths in a single comprehensive field system.

FAQ — What is the operational advantage of using a bell geophone probe versus a contact tip probe during water leak location? The tip probe detects structure-borne vibration by direct contact on accessible network fittings — valves, hydrants, and connection points — making it the correct tool for pre-location surveys along a pipe route. The bell geophone is placed directly on the road or ground surface above the buried pipe, detecting the soil-transmitted acoustic signal radiating upward from the leak — allowing the operator to walk the ground surface and identify the loudest point directly above the leak, without requiring any accessible fitting at the exact leak position.
