ETBT Sonic Belt Tension Tester

The Draper ETBT Sonic Belt Tension Tester is a precision diagnostic tool designed for professional mechanics and vehicle technicians working with drive belt systems. This electronic tester uses sonic measurement technology to accurately assess tension levels on camshaft, timing, and auxiliary drive belts, ensuring optimal performance and preventing premature wear or failure. Using an integrated microphone and flexible probe, the device measures belt vibration frequency to determine precise tension levels. This sonic testing method provides reliable readings even in cramped engine bays where traditional tension gauges struggle to access. The 115mm flexible probe is particularly valuable when working around complex engine layouts or testing belts positioned deep within the engine compartment. The tester features 20 internal memory slots for storing measurement data, allowing technicians to record and compare multiple readings during installation or adjustment procedures. With a frequency range of 10-600Hz, the device accommodates various belt types and widths. An automatic power-off function activates after five minutes of inactivity to conserve battery life. The unit weighs just 242g and measures 165 x 65 x 30mm, making it compact enough for mobile mechanics and workshop technicians alike.
