MarMonix MES 111 Electronic Stethoscope

MarMonix MES 111 Automotive Stethoscope

The MarMonix MES 111 Electronic Stethoscope is a professional diagnostic instrument designed to help technicians, engineers, and maintenance specialists detect hidden mechanical issues before they turn into costly failures. With its wide frequency range from 30 Hz up to 15 kHz, the MES 111 allows you to capture both low-frequency knocking sounds and high-frequency vibrations with remarkable clarity.

Built for automotive repair, industrial machinery inspection, HVAC systems, pumps, compressors, and preventive maintenance programs, this tool gives professionals the ability to listen inside machines and identify faults at an early stage. By using advanced electronic amplification and high-sensitivity probes, the MES 111 transforms otherwise inaudible vibrations into clear, diagnostic signals you can trust.
