Boat engine hour meter RH60

The RH60 Digital RPM/Engine Hours/Elapsed Time gauge is a four digit digital display of engine RPM, total engine hours, elapsed trip time and maximum r.p.m. seen. The RH60 works with any engine and can be driven from a wide range of signal frequencies and amplitudes. Front panel calibration is provided for spot-on accuracy to within 1 RPM. A seperate engine hours countdown alarm can be set to warn you to perform needed maintenance every set number of hours of engine running time. When activated, the RH60 built-in 85 dB alarm will sound and the display will flash. Five levels of backlighting can be selected and all set-up, calibration and alarm values, are saved to non-volatile memory. Data is output on an NMEA 0183 compatible serial data line or that screw terminal can be programmed as an external alarm output.
