The flexible gooseneck probe bends behind appliances and around pipes.

Homeowner-first, not technician-first. LeakHound is designed to make a focused inspection easy to understand, even if you do not work in HVAC or plumbing.

A smell is a warning — not a location

Find the connection that needs attention.

Walk the probe along appliance fittings, gas valves and line connections. When the meter climbs and the alarm speeds up, you know where to focus instead of checking every connection blindly.

Detection range: 0–1,000 ppm

Useful for tracing changes in supported gas concentration while inspecting.

Accuracy: ±0.1%–±0.5% FS

Built to provide a stable reading for practical diagnostic checks.

Color LCD + audible alarm

Use both visual and sound cues so you can keep your attention on the probe position.

Simple enough for a first-time check

The closer you get, the clearer the signal becomes.

Start with a broad sweep, then step down through the three sensitivity levels as you get closer. The rising visual meter and faster audible alarm help you isolate the exact area to inspect.

1

Zero in clean air

Establish a clean baseline before the inspection.

2

Sweep joints & fittings

Move slowly around suspected connections.

3

Lower sensitivity & pinpoint

Use the stronger signal to narrow down the leak source.

Frequently asked questions

Know before you inspect.

Can I use LeakHound HD1 around my gas stove or water heater?

Yes, it is designed to help locate supported fuel gases around common connections such as stoves, water heaters, furnaces, propane systems and similar fittings.

Does it detect carbon monoxide?

No. LeakHound HD1 does not detect carbon monoxide.

Is this a replacement for a hardwired gas or CO alarm?

No. LeakHound HD1 is an inspection tool that only works while you actively use it. Keep proper installed alarms in place and test them according to their manufacturer instructions.

Can I use it for car A/C refrigerant?

It supports refrigerants R22, R32 and R134a. Confirm the refrigerant used by the system you are inspecting before relying on the detector.

How does the alarm help pinpoint a leak?

The audible alarm increases in frequency as detected concentration rises. Combined with the display and sensitivity control, that lets you narrow the search area.
