Zero-Max Handy-Tach SH4150 Mechanical Hand-Held Tachometer With Case And Tips - Used

Zero-Max "Handy-Tach" Model SH4150 hand-held mechanical contact tachometer in its fitted carry case with extension shaft, contact tips and surface-speed wheel. Four selectable ranges (100 / 500 / 1000 / 5000 multiplier) and a CW/CCW rotation switch let you take direct RPM readings from a shaft end or a rotating surface — handy for spot-checking engine, gearbox, pump or generator shaft speed in the shop or on the boat. Application: general-purpose shop and field RPM measurement; not specific to any one engine or transmission, and no application has been verified. Condition: Used, untested. Paint scuffs, corner chips, light surface rust on hardware and general shop soiling. Meter glass intact, pointer at zero. No calibration or functional testing has been performed — accuracy is not warranted. Case contents shown in the photos are what is included; the set may be incomplete. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
