The LD8000 Leak Detector locates and pinpoint leaks in water and pressurized pipe systems – the LD8000 listens for vibrations generated by the pressure change of escaping liquids and gasses. Vibration radiation created by the escaping liquid is collected using a geo-phone ground sensor and fed to Digital Wave Filtering Chips in the main unit. These digital noise filters reduce unwanted noises and interference in the locator’s immediate testing environment and help to highlight the leak cues. Detection capabilities are enhanced with six user selectable band pass frequencies – 100 Hz, 200 Hz, 300 Hz, 500 Hz, 800 Hz and 1,200 Hz. When used at its lowest frequency range of 100 Hz, the bell curve frequency response of the LD8000 makes it suitable for finding leaks in PVC. Leak vibrations and signal strength are indicated to the user audibly through the noise canceling headphones and visually via the integrated LCD panel. Housed in rugged ABS plastic, the LD8000 receiver is designed to withstand the environmental hardships of daily field use. 800.851.7347, www.rycominstruments.com

Locate large diameter mains using the Sahara leak location system. The system uses a tether-controlled sensor that is passed through a pipeline, giving utilities the opportunity to prevent leaks from becoming breaks and saving lost water in the process. Because inspections can be done through an existing 2-inch diameter tap while the pipeline is in service, there is no disruption to water service. The system is inserted into a live main through any tap 2 inches or greater in diameter, and is completely safe for potable water systems. A small parachute uses the flow of water to draw the sensor through the pipeline. PPIC’s surface tracking device allows the position of leaks and other pipeline features to be located to within 18 inches. 877.ASK-PPIC; www.ppic.com
