HIKMICRO AD22P-I/O Indoor & Outdoor Leak Detector | AU

The problem with carrying two kits — or worse, guessing which one you need

Leak detection work rarely announces in advance whether it’s an indoor job or an outdoor one. A call-out for “water coming from somewhere near the bathroom” might turn out to be a slab leak that’s tracked outside the building line. A high water bill investigation that starts at the meter might end up needing a wall cavity check once you’ve traced the line back into the house. For technicians who only carry indoor or only carry outdoor equipment, that kind of job means either turning up under-equipped or making a second trip — neither of which does much for your day rate or your client’s confidence.

The alternative — owning two separate leak detection kits — solves the coverage problem but creates a logistics one. Two units to charge, two cases to carry, two sets of consumables to track, and inevitably the one job that needs the kit currently sitting back at the workshop. For contractors and utility teams whose work spans both indoor plumbing and outdoor service lines as a matter of course, that’s an ongoing tax on every job, not just an occasional inconvenience.

One main unit, two purpose-built sensors

The HIKMICRO AD22P-I/O solves this by combining both sensor types into a single kit built around the same AD22P main unit and 7″ touchscreen used across the range. You get the high-sensitivity indoor sensor for wall, floor, ceiling, and underfloor heating leak detection, and the IP66-rated outdoor sensor for ground-contact detection of buried service lines, courtyards, and paved areas — plus listening sticks for fast, direct-contact checks on exposed pipework and fittings.

The unit auto-recognises whichever sensor is connected, so moving from an indoor wall check to an outdoor ground survey on the same job doesn’t involve any manual reconfiguration — unplug the indoor sensor, connect the outdoor sensor, and the AD22P-I/O adjusts its filtering and mode options accordingly. That matters on jobs where you genuinely don’t know at the outset whether the leak is going to end up being an indoor or outdoor problem, or where it turns out to be both.

Frequency coverage tuned for both environments

Indoor and outdoor leaks produce sound in meaningfully different frequency ranges, which is why the AD22P-I/O gives you dedicated presets for each rather than one generic setting stretched across both jobs. Indoor Mode 1 (5,000–16,000 Hz) and Indoor Mode 2 (8,000–16,000 Hz) are tuned for the higher-frequency sound typical of leaks travelling through building structure, while Outdoor Mode (200–2,000 Hz) is tuned to the lower-frequency signature of water escaping underground. Custom Mode extends across the instrument’s full 200–16,000 Hz range for the leaks that don’t sit neatly in either preset — whatever the pipe material, burial depth, or building construction throws at you.

SuperDetect, HIKMICRO’s automated leak-zone analysis feature, operates in indoor mode to highlight probable leak locations directly on the touchscreen — a genuine time-saver on indoor jobs, and one more reason the combo kit earns its place over carrying a basic listening-only tool for indoor work.

Two inspection workflows, whichever environment you’re in

The AD22P-I/O carries the same two inspection modes across both sensor types. Quick Inspection Mode supports fast, comparative screening — walk a suspected area, compare relative sound levels at a series of points, and narrow things down quickly, whether that’s a room inside a building or a stretch of paving outside it. Route Inspection Mode supports a more structured, multi-point survey for larger or more complex investigations, useful on bigger commercial properties or longer buried service runs where a quick scan alone won’t give you the confidence to commit to a cut or a dig point.

Being able to apply the same locate → localise → pinpoint workflow regardless of whether you’re indoors or outdoors means less mental context-switching between tools and more consistency in how you document and report findings.

Everything in one case

The AD22P-I/O kit includes the AD22P main unit, the indoor sensor, the outdoor sensor, listening sticks, a headset, and a hard carry case to keep the full kit organised and protected in transit. It’s genuinely built as a single, complete solution rather than a bundle of two separate product lines — one case to grab off the shelf before a job, regardless of what that job turns out to need.

A full day’s work, indoors or out

Battery performance doesn’t change based on which sensor is attached — the AD22P-I/O runs up to 11 hours continuously on its rechargeable Li-ion battery, with a 4-hour recharge time, whether you’re spending the morning inside a building and the afternoon tracing a service line outside it. Audio findings are saved in .wav format for review on PC, and image captures in .jpeg for documentation, with USB 2.0 (USB Type-C) connectivity for pulling data across for reporting once you’re back at the office.

Who the combo kit makes sense for

Full-service leak detection contractors who don’t want to turn down a job because it’s the “wrong” kit day. Plumbing companies fielding a mix of indoor plumbing call-outs and outdoor water-bill investigations from the same client base. Water utility contractors whose work regularly spans from the meter, along the service line, and into the building. Facility management teams responsible for both the building envelope and the surrounding grounds, where a leak investigation might legitimately need to go either way depending on where it leads. In every case, the value of the AD22P-I/O isn’t just having both sensors — it’s not having to predict, before you arrive on site, which one you’re going to need.

Backed by local support that understands the trade

We stock and support the full HIKMICRO acoustic leak detection range for Australian trade professionals, including advice on which kit configuration fits your actual job mix. If most of your work is squarely indoor or squarely outdoor, the dedicated AD22P-I or AD22P-O kit may be the more cost-effective choice — we’re happy to talk through the difference so you’re not paying for sensor coverage you won’t use. For contractors genuinely working across both environments, the AD22P-I/O is built to be the only leak detection kit you need to carry.

Technical Specifications

What is the HIKMICRO AD22P-I/O used for? The AD22P-I/O is a combined acoustic leak detector kit that includes both an indoor sensor and an IP66-rated outdoor sensor, allowing technicians to investigate leaks inside a building and in outdoor service lines or paved areas using a single device.

Why choose the AD22P-I/O over the separate indoor or outdoor kits? The combo kit removes the need to predict, before arriving on site, whether a job will end up being an indoor or outdoor leak investigation — both sensors are included, and the unit auto-recognises whichever one is connected.

Does the AD22P-I/O sacrifice anything compared to the dedicated indoor or outdoor kits? No — it uses the same main unit, the same indoor and outdoor sensors, and the same frequency ranges, inspection modes, and SuperDetect functionality found in the individual AD22P-I and AD22P-O kits, combined into one kit.

How does sensor switching work on the AD22P-I/O? The device auto-recognises which sensor is physically connected — indoor or outdoor — and adjusts its available filter presets and modes accordingly, with no manual configuration required.

Can the AD22P-I/O detect both a wall-cavity leak and a buried service line leak on the same job? Yes — that’s the specific scenario this kit is designed for, using the indoor sensor for the building-envelope portion of the investigation and the outdoor sensor for the buried or exterior portion.

How long does the AD22P-I/O run on a single charge? Up to 11 hours of continuous operation from its rechargeable Li-ion battery, with a 4-hour recharge time, regardless of which sensor is in use.

Who is the AD22P-I/O best suited for? Full-service leak detection contractors, plumbing companies, and water utility field teams whose work regularly spans both indoor plumbing investigations and outdoor property-side or service line leak detection.
