Leak Detection Made Easy with the Goldak 777-B

Plumbers, contractors, water works personnel, and maintenance teams rely on specialized equipment for detecting underground water leaks. The Goldak 777-B meets this need with exceptional precision, utilizing the proven principle that leaks in pressurized water systems create mechanical vibrations that travel along pipes and through surfaces.

Simple Operation for Accurate Results

All three microphones used for leak detection are user-friendly. Simply touch the microphone probe to the pipe or exposed fittings like hydrants, shut-offs, valve stems, faucets, and more. The microphone converts mechanical vibrations into electrical impulses, which are then amplified, allowing the operator to hear the sounds of the leak through headphones. Localizing the water leak is done by comparing readings and sounds from different points in the water system.

Ready for Any Job – Three Included Microphones

1. M-79 Series 2 Microphone - Ultra-sensitive, disc-shaped microphone designed for maximum sensitivity and sound quality. Comes with a microphone cable and is standard with all Goldak Model 777 leak detectors.
2. NE-77 "Noise Eliminator" Microphone - Ideal for high-noise environments. This microphone mutes external noise such as wind and construction, making it perfect for detecting leaks in challenging conditions.
3. 71C-007 Microphone Probe - A standard 12" long probe for direct contact with test points like pipes, valves, or concrete slabs, allowing for precise leak detection.
