The Hikmicro AD21P acoustic leak detector uses advanced sound processing techniques to detect sound waves from water leaks. These sound waves are converted into sounds and numbers that the human ear can hear. Read more.
The HIKMICRO AD21P acoustic leak detector is a professional leak detector (ground microphone) for accurately locating leaks in compressed air, gas, and vacuum systems. Using ultrasonic technology, the AD21P detects leaks that are neither audible nor visible using traditional methods. This makes the device indispensable for maintenance technicians, installers, and technical services looking to minimize energy loss and prevent malfunctions.
An acoustic leak detector, also known as an ultrasonic leak detector, locates leaks by detecting high-frequency sound waves created when gas or air escapes under pressure. These sound waves are inaudible to the human ear, but the HIKMICRO AD21P converts them into an audible signal. This allows a leak to be located quickly and precisely, even in environments with high background noise.

The HIKMICRO AD21P acoustic leak detector (ground microphone) is an advanced, high-performance instrument designed for technicians and plumbers to detect leaks in pipes, water systems, and both residential and commercial buildings. The device uses advanced sound processing techniques to capture sound waves from water leaks, converting them into audible sounds and measurable values.
With four adjustable digital bandpass filters and a gain of up to 80 dB, the AD21P provides precise filtering and amplification of sound frequencies, making it easy to locate leak points. The system uses sound waves and shock waves: when water flows through a leak point, specific sound waves and shock waves are produced, which are received and analyzed by the detector to pinpoint the leak location.
The AD21P is versatile, featuring both a handheld and pick-up sensor, enabling detection of even difficult-to-detect leaks. This helps reduce resource waste and loss and ensures efficient leak detection in pipes and systems.
