The parabolic probe for the SONAPHONE devices identifies sound emissions in the ultrasonic frequency range caused by compressed air leakages and electric partial discharges. The leakages within compressed air systems, industrial plants and machineries as well as within pipes difficult to access are detected quickly and reliably. Even leakages that are up to 20 m away from the testing site are detected due to the great operating distance of the SONOSPOT.

The use of the SONOSPOT leads to a reduction of energy costs and to a higher safety in operations since damages can be identified at a very early stage. The high sensor sensitivity and the very precise directivity allow the detection of electric partial discharges and isolation damages, e.g. at medium voltage installations.

The parabolic probe possesses an integrated red dot sight which leads to a precise detection of the ultrasound source. The insensitivity to background noises in the acoustic noise range is an optimal condition for applications within noise intensive areas, such as factory floors. The optimal ergonomics and the light weight enable an easy handling and transportation.
