Xmic
Xmic is an advanced, yet easy to use electronic ground microphone. It is designed to amplify the noise generated by water escaping from buried supply pipes under pressure. The latest acoustic and amplification technology provides excellent sound quality, whilst a range of features help effective and accurate pinpointing on site.
MLP - Minimum Level Profiling
Having identified an area of potential leakage, Xmic assists the operator to pinpoint the leak position. MLP checks the readings over the previous 3 seconds and memorises the lowest noise level. This is the constant background (leak) noise. As the sensor is moved, a series of readings are taken. These are displayed digitally and graphically to clearly show the leak position.
Auto and Manual Filtering
The operator can select metal or plastic filters at switch on; Xmic automatically sets filters for the pipe material. To further suppress background noise and target the leak, manual filtering allows the filter pass band to be positioned anywhere within the filter range. The selected pass band is displayed graphically.

Key Features
- Automatic or manual filtering to suppress background noise and target leak noise.
- Lightweight portable amplifier module.
- Large backlit multi-function display showing digital and graphical noise level and dynamical sensitivity (signal strength) to pinpoint leak.
- 'Analogue' style moving meter gives quick representation of noise level trends.
- Levels of leak noise can be recorded for comparison in a histogram profile (MLP).
- IP65 enclosure with mil-spec connectors.
- High quality sound.
- Battery level indicator.
- Magnetic contact on hand probe provides better coupling to fittings, which in turn provides clearer, louder audible leak noise.
