Key Features Measurement range: 800–50,000 RPM, enabling monitoring from low idle to high-speed operation across a broad set of engines and rotating machinery. Resonant-wire readout: a sensing wire extends from the unit; when the wire is in resonance with the engine, it vibrates and the RPM is read from the scale. Direct scale readout: RPM is read directly from the integrated scale for quick diagnostics without additional tools. Manual calibration: simple adjustment by turning the top disc to align readings with the scale. Frequency measurement: capable of measuring vibration frequency in the range 14–750 Hz in addition to RPM. Compatibility: suitable for use on most engines and rotating machinery. Product Details Model: Briggs & Stratton Tachometer - 19200E Measurement principle: vibrating wire resonance; the wire extends from the unit and vibrates when in resonance with the engine, with RPM read from the scale. RPM range: 800–50,000 RPM Frequency range: 14–750 Hz Readout method: direct RPM reading from the scale; designed for straightforward operation and quick maintenance checks. Intended use: suitable for engines or other rotating machinery requiring RPM and frequency data; emphasizes accuracy and ease of use. Compatibility Designed to be used on most engines and rotating machinery where RPM and frequency data are required.
