The RD546 is a mechanical listening stick made from high-quality materials for water leak detection at meters, pipes and other fittings.

Even with today’s sophisticated technology, mechanical measurement instruments offer unique and cost-effective advantages. Many situations do not require any sensitive electronics and it is often more practical to use the RD546, which does not require a power supply and does not have the inherent noise associated with electrical products.

The RD546 is made of high-quality materials. The vibration element inside consists of a bronze spring that is designed to transfer vibration via a resonator to the operator’s ear. Stainless steel extensions, from 5 to 78 inches (13 to 200cm), make the RD546 adaptable to any task. The RD546 is the ideal, low tech and, cost-effective solution for detecting leaks in meters, pipes and other fittings.
