Digital Tachometer and Hour Meter – Stay on top of your maintenance schedule
Is your engine running, but you have no idea how many hours it has clocked? Or perhaps you’re pushing the revs without knowing the actual speed? This often leads to missed service intervals, premature wear, and unnecessary repair costs. Our digital tachometer and hour meter solves this instantly—simply and effectively, with no complex wiring or professional installation required.
Note: This device uses inductive signal reading. The signal cable simply wraps around the spark plug wire, meaning there is no need to cut or modify your engine’s existing electrical system.
Why choose this model? (Key Benefits):
- 2-Minute Installation — No special tools or electrical modifications needed; simply wrap the cable around the spark plug wire and you’re ready to go.
- Universal 2T/4T Compatibility — Perfect for motorcycles, ATVs, scooters, boats, generators, chainsaws, tillers, brush cutters, and agricultural machinery.
- Wide Measurement Range — Displays 0–99,999 RPM and supports high-performance engines up to 25,000 RPM, including high-power chainsaws.
- Resettable Hour Meter (up to 10,000 hours) — Track your oil changes and service intervals precisely, no more guesswork.
- Waterproof Design — Built for permanent mounting on equipment exposed to rain, mud, or moisture without risk of damage.
- Long-Life CR2032 Battery — Includes a battery with a 2–3 year lifespan that is easy to replace without losing your recorded data.
Performance and Specifications
The device operates via inductive sensing—no wires are cut, and there is no interference with the engine’s electrical system. The cable wrapped around the spark plug wire captures the signal and transmits it directly to the LCD display, which shows both real-time RPM and accumulated engine hours. The sealed housing makes it ideal for fixed mounting on generators, brush cutters, or ATVs, regardless of weather conditions. The included mounting kit ensures a secure fit on frames or handlebars without any makeshift solutions.

Programming and Usage Instructions
- Unwind the signal cable and wrap it 3–5 times around the spark plug wire for a stable and accurate signal.
- Secure the tachometer to the frame, handlebar, or any flat surface using the provided mounting hardware.
- Start the engine — the LCD display will automatically show the RPM in real-time with no further configuration needed.
- To select the 2T or 4T mode, press the configuration button as detailed in the manual (the number of wraps can influence reading accuracy).
- To reset the hour meter, hold down the dedicated button according to the included instructions.
- Replace the CR2032 battery when the display dims — your recorded data remains saved in the internal memory.

Frequently Asked Questions
Does this work on diesel engines?
No. The reading is based on the inductive signal from a spark plug, and diesel engines do not use spark plugs. This device is exclusively compatible with 2T and 4T petrol engines.
Do I need to cut or modify any engine wires?
No modifications are required. The signal cable wraps around the spark plug wire without direct electrical contact—the installation is completely non-invasive.
Will the hour meter reset if I remove the battery?
No. Data is stored in the internal memory and is not lost when replacing the battery. The meter can only be reset by manually pressing the dedicated button.
Is it compatible with 4-stroke petrol generators?
Yes, it is fully compatible. It accurately monitors RPM and operating hours—exactly what you need to schedule oil changes and periodic maintenance correctly.
What is the maximum RPM it can display?
The display covers 0 to 99,999 RPM, and the device supports engines with speeds up to 25,000 RPM—including high-revving chainsaws and professional equipment.
