UMA Tachometer | 3-1/8 in, 0–3500 RPM, 1.5 pulse/rev, Color Marking, TSO C49b, No Internal Hour Meter HW3X11S48B and the parts tray baseUMA 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.
