UMA TSO Tachometer | 3-1/8 in, 0–3500 RPM, 2 pulse/rev, Custom Markings

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. To the mechanical drive, use UMA's TIA3-4 sending unit, 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.
