Replacement and upgrade for the GS-1000.
The GS-5100A is a long range contact type linear gauge sensor which has a linear type displacement converter and converts spindle displacement directly into electric signals.
The adoption of ball bearings in the spindle has resulted in increased torsional rigidity ( practical durability of more than 15 million cycles ).
High accuracy gasoline engine tachometer measures rpm on 2-cycle (1,2,3 cylinders) 4 - cycle (1,2,3,4,5,6,8,12 cylinders). Small & thin enough to fit in your shirt pocket. For quick and easy RPM measurement, simply bring the detector close to the high-tension cords of the engine. Upgraded and replacement for the SE-1100.
