Faria Beede Instruments TD9122B 4 Tachometer Euro Style - 4000 RPM Diesel - Bulk Case of 12

This Euro Style 4 Tachometer is designed for diesel engines with a maximum capacity of 4000 RPM. Featuring a 3.375-inch (85mm) mounting hole, the tachometer boasts a clear, perimeter-lighted black dial with bold white graphics, complemented by a black aluminum SAE style bezel and a contoured white pointer behind a flat glass lens.

It operates by counting pulses from the ignition system, alternator, tach signal generator, or magnetic pickup sender. Connect it to +12vDC and ground, then choose the appropriate signal source to match your engine's requirement.

Easy to set up, this tachometer allows for precise readings by adjusting the switch to the correct position corresponding to the number of engine revolutions per pulse.
