UMA Tachometer | 3-1/8 in, 0–3500 RPM, 2 pulse/rev, Black & White Dial, TSO

UMA TSO certified analog tachometers are designed for most Continental and Lycoming engines with a mechanical drive or magneto ignition. They are available with or without a built-in hourmeter. The mechanical drive uses UMA's TIA3-4 sending unit that is set up for a 1:2 drive ratio which replaces the mechanical cable. A magneto pickup may also be used, UMA's T1A9-(x) that installs in the inspection plug of the magneto housing. 

This tachometer (EDMO# T19801102) fits a 3-1/8 inch mounting hole, has a 0 rpm – 3,500 rpm range, 2 pulse/rev, and Black & white dial.
