The SL2000 in the Trotec MultiMeasure series is a modern, easy to operate leak detection unit with which leakage information can be evaluated both in the audible range and also in the high-frequency ultrasonic range.
If water or air escapes under pressure, a noise is generated that propagates as structure-borne noise in the pipework material and can be pinpointed by listening to it. These noises contain both audible sound and ultrasonic. Ultrasonic cannot be heard by the human ear.
