DatasheetThe HIKMICRO Acoustic Leak Detector AD21 is a high-performance device designed for technicians and plumbers
to find leaks in plumbing, water service, and residential or commercial properties. The device has four ranges of
selectable digital bandpass filters, and the amplification is up to 80 dB. The filtration and amplification of the sound
frequencies can help you locate the leakage points accurately. It can be widely used with the handheld sensor and
pick-up sensor correspondingly. Furthermore, it can detect ignored leaks, reducing resource waste and property
loss.
