Description
The SubSurface LD-12 is the ultimate Leak Detector for customizaton and versatility. For range, the LD-12 offers six frequency filters, with low side filters (100Hz, 200Hz, or 400Hz) and high side filters (600Hz, 800Hz, or 1200Hz). In addition, the Filter-Thru switch feature can turn the filters off, enabling the whole range of 50Hz to 15,000Hz.
The combo of both noise amplication and reduction selectively filter audio. The protective “limiter” switch cuts off all loud noises greater than 110dB. Plus, the high-sensitivity ground microphone and low electronic noise amplifier zero in on nothing but the leak sounds.
The Ld-12 comes with three accessories for attachment to the sensor: ground plate for pinpointing on concrete, magnet base for surveying at hydrants or valves, and contact rod for surveying at meters.
Other features include a large, back-lighted meter display for sound loudness, and amplifier weighing only 31 ounces, with a padded carrying case and strap.
