With digital noise reduction that removes intermittent sounds like barking dogs and passing vehicles. DNR-18: the advanced digital CPU eliminates intermittent interfering noises, like passing vehicles, people talking, and pedestrian footsteps.
Traditional band-pass filters filter continuous noises, such as A/C hum, idling motors, and wind. While traditional filters are very useful, they are not able to filter out the common, intermittent noises with broad frequency ranges.
DNR-18 has optional accessories for water leak "pinpointing" and water leak "surveying".
Graph the leak sound levels at 5-10 spots directly over the pipe. Let the DNR-18's amplifier pinpoint the leak's location for you instead of relying upon your hearing.
This is the High Performance acoustic leak detector.
It has been 10 years since the HG-10All went on sale and this has built a solid reputation due to useful hand-switch and light weight sensor. It allows accurate pinpointing of the actual leak.
HG-10All professionals Water Leak Detector has optional 3 contact rod for Water leak surveying.
The LD-7 is the smallest and lightest-weight water leak detector yet it has a very sensitive ground sensor. With the listening rod connected to the ground sensor, listen to the sounds of water-leaks transmitted to faucets, meters and valves.
Whether your needs are for water leak surveys or for water leak pinpointing in service lines or in buildings, the LD-7 offers excellent performance at a very reasonable price.
The FSB-8D is a small, compact electronic sound detector for finding water leaks.
Especially, FSB-8D is well-suited to Water Leak Surveying on pipe of Plastic pipes like PVC and PE.
The new-generation lightweight LC-2500 brings a new dimension to leak detection.
It's extremely portable and easy to set up and run. Input pipe materials, pipe diameters, and lengths between Red and Blue sensors by simply selecting them in the program menus. The automatic functions can do the rest.
The Main processor Unit displays the correlation "picture" and the distances to the leak from the Red pre-amp transmitter and the Blue pre-amp transmitter.
Simple and light Measuring Wheel B20-s can measure up to 10,000m at 10cm graduation.
The counter is indicated in 5 digits and has reset button. When we use Leak Noise Correlator LC-2500, we need to input the between pick-up sensors.
Fuji Listening stick is the Oldest but extremely effective at Leak Surveying.
Individual service connection survey is widely practiced by Japanese Non-revenue water specialists. An optimum designed resonance chamber amplifies the leakage noise from various kinds of pipe materials.
Fuji Listening stick is the simplest and useful device. LS-1.5m, LS-1.0m, Separable Type (30cm) is available.
After marking the leaking point on the ground, make a hole at the marked point by use of the boring bar and insert the Listening Stick into the hole to confirm the leaking point as near as possible.
Fuji boring bar saves you excavation cost.
