The LeakFinderRT Mini is a leak noise correlator for locating leaks in all types of water and other fluids transmission and distribution pipes. It provides the same features and advantages of the LeakfinderRT system in a smaller and lighter package using the same software. It’s ideal for situations where the ruggedness and longer battery of the LeakFinderRT is not needed. LeakFinderRT Mini uses advanced sensor technology and signal processing to make the system more effective when correlating small leaks or when high background noise is a factor. Also, an enhanced correlation function has been integrated to improve the definition of correlation peaks for narrow band leak noise. This is important for multiple leak situations, plastic pipes or in settings where leak sensors have to be closely spaced. The base model comes with: a wireless receiver; two wireless transmitters; two high sensitivity accelerometers; a stereo headphone set; AC battery charger; USB cable; two low temperature-rated sensor cables and waterproof rugged Pelican carrying case; and an optional netbook. 866.324.6564,

SubSurface Instruments
SubSurface_leak detect_LD-12.jpgSubSurface offers a professional water leak detector with a standard cable. A large meter display (with backlight) of sound loudness, allows the user to pinpoint the exact leak location. The unit includes a light-weight amplifier (31 ounces) with a padded carrying case and a strap. The locator has six selectable filters, split into three "low side" filters (100Hz, 200Hz or 400Hz) and three "high side" filters (600Hz, 800Hz or 1200Hz). A “Limitter" switch which cuts off all loud noises greater than 110dB. A "Filter-Thru" switch turns off all of the amp's filters, allowing the user to hear all sounds from 50Hz to 15,000 Hz. High-sensitivity ground microphone and low "electronic noise" amplifier combine to offer quality sounds for leak detection. Three accessories for attachment to the sensor are included: a ground plate for pinpointing on streets/slabs; a magnet base for surveying hydrants/valves; and a contact rod for surveying at meters/fittings. 920.347.1788,
