ST20 Listening Stick

Low Cost Mechanical Leak Detection

The high performance ST20 Listening Stick uses mechanical amplification for detecting and pinpointing leakage and has an acoustic resonant chamber for noise amplification.

The three segment plated steel bar transmits the leak noise vibrations to a brass diaphragm within the resonant cavity. The radiated noise is mechanically amplified within the chamber to improve sensitivity.

Made from chromium plated mild steel, it is suitable for basic level leak detection and ideal for individuals who may experience difficulty in differentiating between static and leak noise on an electronic listening stick.
