xOverview
Meet the DDayuanwei Small Engine Tachometer, a compact, IPX68-rated gauge designed for petrol engines. It delivers RPM readings up to 36,000 with 1% accuracy, tracks operation hours from 1 to 9,999, and refreshes every 0.5 seconds for near real-time insight. Built for durability, it withstands challenging conditions while remaining easy to set up and use on the go.
Two backlight modes and safe sensing
The tachometer features a green backlight for clear visibility in dim environments and a red backlight that signals when RPM crosses a programmable threshold. It uses a clip-on inductive sensor to detect ignition signals, eliminating the need for external power connections and reducing wiring clutter.

Two measurement methods
Choose between clamping the spark plug wire to receive the signal or using the inductive measurement method. The recommended sensing distance is 3–5 cm, offering safe, reliable readings without direct contact with high-voltage components.
Multifunction display and power care
Beyond RPM, the device acts as an hour meter and offers features such as TOT, JOB, SVC, MAX RPM, RPM alarm, clock, auto sleep, and data memory. If the battery low indicator appears, replace the battery to preserve data while readings remain accessible.
Wide range of applications
Suitable for a broad spectrum of gasoline engines and tools, including chainsaws, hand-pushed mowers, weed whackers, motorcycles, ATVs, boats, outboards, go-karts, and small workshop machines. It is designed for safe, practical monitoring of engine performance in everyday use.
Overall, this tachometer offers actionable readings, practical alarms, and flexible installation options to help you monitor performance and plan maintenance with confidence, rather than promising guarantees. Use it as a helpful tool to guide routine checks and preventive care for your equipment.
