SMARTACH (118-9913)

Designed for use on any engine equipped with an alternator, and only requires a simple connection to the electrical system (e.g. battery, alternator, cigarette lighter connector) to measure engine RPM. Taking advantage of the ripples generated by the alternator, SMARTACH automatically calculates the relationship between the speed of the engine and the alternator ripples, and uses them to measure RPM on any piston engine regardless of its ignition system (Diesel or gasoline). Measures from 2.5 to 99999 RPM. 0.05% accuracy. 2 to 20" measuring range. Laser-powered optical system. Large 4½ digit LCD display. For 1 to 12 cylinders and 2 or 4 cycle engines. Memory recall functions (minimum & maximum). Comes with hard shell carrying case
