85mm Tachometer with Hourmeter
| Diameter | 85mm |
|---|---|
| Type | tachometer with integrated LCD hour meter |
| RPM range | 0-4000 or 0-8000 (0-3000 on special order, min 25) |
| Signal source | W terminal or inductive sensor |
| Signal type | 2- and 4-cycle; square or sine wave |
| Power | 12V or 24V (24V via dropping resistor or voltage regulator) |
| Backlight | red or amber |
| Waterproof rating | IP67 |
| Face | black or white |
| Bezel | black or white plastic, or 316 stainless |
An 85mm rev counter with a built-in LCD hour meter, so you can read engine speed and track total running hours from one gauge. Stocked in 0–4000 and 0–8000 RPM versions; a 0–3000 RPM version is available as a special order (minimum 25 units — ask us).
It takes its signal from a W terminal (alternator) or an inductive sensor, and handles both 2- and 4-cycle engines and square- or sine-wave signals — so it works with most petrol and diesel set-ups once the signal source and pulses-per-rev are set correctly. Because that varies from engine to engine, it's worth reading the tachometer setup guide and the tachometer FAQs before fitting, or having it wired by someone familiar with engine instrumentation.

Fitting on 12V or 24V — and why a voltage regulator helps
A 12V system is never a steady 12V: it sags under load, rises to 14V or more on charge, and spikes as things switch on and off. The gauge sees all of it, so readings can wander with the state of the electrics rather than with what you’re measuring. A voltage regulator delivers a clean, steady voltage whatever the supply is doing — so the gauge reads consistently, the backlight stays even, and sensitive electronics are protected from spikes.
On a 24V system a dropping resistor is supplied to suit the gauge, but a regulator is the better option: resistors run hot, waste power and add a failure point at each gauge, whereas one regulator feeds the whole dashboard from a single clean supply (the 3A model runs up to 20 standard 52mm gauges, the 5A up to 38).
