The Mikron3 ground microphone enables very high quality surface listening to confirm position. The Mikron3 App is selected on PrimeTouch, which also hosts Eureka3, thereby combining correlation and leak listening on a common platform. The touch screen provides very simple operation.

Minimum Noise Level Display

Leak noise propagates from the leak to the ground surface where it can be detected using the sensitive ground microphone. For accurate leak pinpointing Mikron3® displays the Minimum Noise Level. This is the background noise level, including the leak noise, but without transient noises such as traffic.

Frequency Display

To further enable accurate pinpointing Mikron3® also displays the frequency content detected as a bar graph. This will increase as the sensor is positioned closer to the leak.


Ground Microphone: Once the leak area has been defined then pinpointing is carried out using the ground microphone on flat surfaces. This provides excellent isolation from airborne noises due to the rubber cushioned housing plus wireless communication.

Tripod Adaptor: The tripod adaptor is fitted to the base of the ground microphone for use on rough ground and softer surfaces.

Hand Probe: The direct input is also available for connecting the correlator accelerometer used as a hand probe.

Dynamic Hearing Protection

Dynamic Hearing Protection monitors the detected noise level. If a very loud noise is detected the the sound in the headphones is muted to protect the user from excessively loud noises.

System Components

The Mikron3® PrimeTouch kit is designed to be used with Eureka3® leak noise correlator.
It consists of the following components:
– Ground Microphone Sensor
– Sensor Handle
– Battery Charger
– Carry Case
