DNR-18 - Digital Acoustic Water Leak Detector (Industrial)1

Made in: Japan
Manufacturer: FUJI TECOM Inc.

The newest detector can process the leak sound digitally and can reduce traffic noise or others disturbing your leak detection-work!
DNR-18 featuring an original Noise Reduction System enables the operator to pinpoint difficult to find leaks in noisy environments during the day!
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.
