AquaLeak 300 – Water leak detector

The Gastech AquaLeak 300 is a compact electronic water leak detector for fast and accurate leak location on both buried water distribution networks and indoor domestic and commercial piping systems. The unit weighs 700 grams with dimensions of 220 x 150 x 200 mm, powered by a built-in rechargeable LiIon battery — distinguishing it from the AA alkaline battery-powered AquaLeak 400 in the same series. The display is a color LCD screen that shows leak noise signal strength in real time as the operator moves along the survey route. A single supply configuration is available — the AquaLeak 300 SC — which includes the instrument body, Bell probe with geophone sensor, HiFi capsule headphones, carry case for transport, and operating manual. The system is CE marked and compliant with the 2004/22/CE directive.

The high-sensitivity geophone Bell probe detects leak noise transmitted upward through the ground from the buried pressurized pipe to the surface — the operator places the probe on the road or ground surface above the pipe route and moves it progressively along the pipe path. The high-gain amplification electronics boost the low-amplitude acoustic signal from the geophone and output it simultaneously to the color LCD display and the HiFi headphones, giving the operator both a visual bar graph and an audio signal that increases as the probe approaches the leak source. High-efficiency digital filters remove ambient urban interference — including traffic, machinery, and wind noise — from the output, isolating the frequency signature of the leak from background contamination. The compact and lightweight body makes the instrument practical for carrying and positioning across extended sequential ground-surface surveys.

The Gastech AquaLeak 300 is deployed by water network operators, municipal water utilities, plumbing contractors, and leak detection specialists for ground-surface acoustic pre-location and location of leaks on buried water mains, service connection pipes, and distribution network sections — particularly as an entry-level instrument for systematic survey programs covering large sections of distribution network, where a single Bell probe configuration covers the majority of survey requirements without the need for additional probe types.

Leader Infra supplies this rechargeable LiIon-powered, color LCD electronic water leak detector for water network operators and plumbing contractors — delivering high-sensitivity geophone Bell probe acoustic leak location with digital filtering and HiFi headphone output in a compact 700-gram instrument suited for both network-scale surveys and individual property investigations.

FAQ — What is the key hardware difference between the AquaLeak 300 and the AquaLeak 400 in the Gastech series? The AquaLeak 300 uses a built-in rechargeable LiIon battery and ships with a single Bell probe geophone configuration only. The AquaLeak 400 uses three AA alkaline batteries — eliminating recharging requirements in the field — and is available in three supply configurations that include the Tip probe piezo-resistive sensor and stabilized tripod alongside the Bell probe, giving the 400 broader probe coverage for contact-point surveys at valves and fittings in addition to ground-surface detection.
