AD21P
The HIKMICRO AD21P is a high-performance acoustic tool engineered to pinpoint leaks with surgical accuracy. By combining a wide-frequency acoustic sensor with the proprietary SuperDetect algorithm, the AD21P filters out environmental noise to isolate the specific sound of pressurized water escaping. It is the ultimate non-destructive solution for energy auditors and plumbing professionals.
Key Professional Advantages
Intelligent SuperDetect™ Technology: This proprietary algorithm automatically analyzes sound frequency and intensity to distinguish between normal pipe flow and actual leaks. It provides clear visual cues on the display, allowing even first-time users to achieve professional-level accuracy.
Four Digital Band-Pass Filters: Effectively silence disruptive background noise. The AD21P allows you to switch between Low, Mid, High, and All-Pass filters (150 Hz to 7500 Hz) to "tune in" to the specific frequency of a leak behind thick walls or under flooring.
Dual Inspection Modes:
Quick Mode: For experienced users who need to pinpoint a known leak area immediately.
Route Mode: A systematic, step-by-step mode for beginners or large-scale facility audits to narrow down the leak source.
Active Hearing Protection: The included high-quality noise-canceling headset features an "Auto-Mute" function. If a sudden, loud noise occurs (like a dropped tool), the device instantly cuts the audio to protect the operator's hearing.
7-Inch LCD Touchscreen & Dual-Wheel Design: The massive 1024 x 600 display provides a clear visual interface, while the physical dual-wheel design allows for rapid volume and filter adjustments—even while wearing heavy work gloves.
Rugged Multi-Sensor Kit: The system includes both a handheld probe for spot-checking and a high-sensitivity pick-up sensor (IP66 rated) for ground-level monitoring.
