TheMTH103E Tachometer / Hourmeter / Overspeed replaces the MTH-103D. Ideal for any application requiring accurate measurement of engine or turbine speed with over / underspeed shutdown in remote locations and hazardous areas. The display provides 5 active digits for high speed turbine applications No DC supply is required, just a pickup sensing the flywheel teeth.
