Gexmil Handheld Digital Tachometer – Induction RPM Gauge For 2-Stroke & 4-Stroke Small Engines (Chainsaws, Lawn Mowers, Etc.)

Got a small engine that’s acting up? This Gexmil digital tachometer is a handy tool to check the RPM (revolutions per minute) of your chainsaw, lawn mower, trimmer, motorcycle, generator, or other 2-stroke or 4-stroke gasoline engines. It measures from 100 to 20,000 RPM with 1% accuracy, and it also tracks total engine running time (up to 99,999 minutes). The LCD screen is easy to read, and it runs on a built-in CR2450 button battery. The best part? It’s inductive – so you don’t need to wire it into the engine. Just wrap the included wire around the spark plug cable or clip it on, and hold the unit near the plug wire. It automatically turns on when the engine runs and goes into power-saving mode when it stops. You can set it for different stroke modes (factory default is 02 for common engines). It’s compact, easy to use, and helps you tune your engine for better performance or diagnose issues like misfires. Perfect for DIY mechanics, landscapers, or anyone who maintains their own gear. Just remember, it’s a manual tool, so there might be a tiny margin of error. Keep it in your toolbox for quick checks. A small investment that can save you time and guesswork!
