UNSPSC 25191802: Dwell tachometer

A device that measures the angle of cam and number of engine rotations.

UNSPSC 25191802 Dwell tachometer is a Commodity code that classifies engine diagnostic and timing measurement instruments used to monitor dwell angle — the duration in degrees of crankshaft rotation during which ignition points remain closed. State and local governments procure dwell tachometers primarily for fleet maintenance and vehicle servicing operations, particularly within transportation departments, public works agencies, and school district maintenance shops that support internal combustion engine repair and tuning. The instruments combine tachometer and dwell-meter functions to enable technicians to verify ignition timing and point gap settings on gasoline engines, making them essential tools for preventive maintenance programs on aging light-duty and medium-duty fleet vehicles.
