The Mk3 80mm ETB electronic tachometer is exceptionally accurate and suits the vast majority of ignition systems. The unit can be switched from 1 to 16 cylinder petrol engines as well as diesel engines (driven via the alternator).
Stepper motor movements are used to give excellent accuracy and smooth operation over the 270° span. Lighting is via 2700k white LEDs to match the ETB 52mm range of gauges.
The tachometer has a programmable output as standard for external shift-lights.
Available in various RPM ranges (as above). The standard format of the 80mm tachometers is RPM x 100. RPM x 1000 is available at extra cost.
