MTH6-1 (20700158): Digital Tachometer and Hourmeter
MTH6-1(240).jpg The MTH6-1 is a microprocessor-based digital tachometer and hourmeter with a built-in overspeed shutdown or alarm switch. It measures speed and running hours and can give an alarm or shut down the engine on overspeed.

The MTH6-1 case is polycarbonate, and its dial measures 3-1/2 in. (89 mm) in diameter. RPM data for the tachometer and overspeed switch is supplied by a magnetic pickup or battery charging alternator. It's 5-digit, liquid crystal display is updated every second.

The magnetic pickup is installed into the flywheel housing of an internal combustion engine. The starter ring gear acts upon the magnetic pickup to generate a voltage pulse each time a gear tooth passes the end of the sensor. This makes calibration simple - just enter the number of pulses per engine revolution and the overspeed set point value using the membrane switches located on the front of the unit.
