It’s designed for technicians, hobbyists, and equipment owners who need fast, portable RPM checks on chainsaws, lawnmowers, motorcycles, ATVs, boats, generators and more. The unit supports single‑to‑eight cylinder counting, includes a reset feature for recorded time and speed, and saves power by automatically turning off when the engine is idle.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the HFWHOK tachometer measure engine RPM?\u003c\/h3\u003e\n\n\u003cp\u003eThe device senses ignition pulses without mechanical contact using an inductive pickup. You either clip the included metal clip to the spark wire housing, wrap the pickup around the wire sleeve, or hold the unit 3–5 cm from the spark plug wire sheath to record RPM.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eInductive sensing for non‑intrusive measurements.\u003c\/li\u003e\n  \u003cli\u003eClip or wrap attachment for secure connection to spark wires.\u003c\/li\u003e\n  \u003cli\u003eHandheld proximity mode for quick checks without clipping.\u003c\/li\u003e\n  \u003cli\u003eCounts pulses for 1–8 cylinder engines automatically.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat accuracy and range can I expect?\u003c\/h3\u003e\n\n\u003cp\u003eThis tachometer reads between 100 and 30,000 RPM with a stated accuracy of about 1%, suitable for most small combustion engines.
