Timorn Small Engine Tachometer — Waterproof Digital RPM & Hour Meter, IP67 Compact Monitoring

The Timorn Small Engine Tachometer is a waterproof digital RPM and hour meter that monitors engine speed, logs total and job run time, and alerts you when maintenance is due.

Compact and built for field use, this Timorn tach/hour meter combines real-time RPM readout with an unresettable total-hours counter and a resettable job timer. It fits a wide range of small engines—generators, lawn equipment, outboards, ATVs, dirt bikes and more—using an inductive pickup around the spark plug wire. Rugged IP67 waterproofing, programmable rev limits, and a recall for peak RPM make it a practical diagnostic and maintenance tool for both hobbyists and professionals.

How will this tachometer help me diagnose engine issues?

The digital RPM display shows current engine speed and stores the highest recorded RPM, which helps identify misfires, idle problems, or governors running out of range. Programmable rev limiter settings let you set safe RPM thresholds to avoid over-revving during testing or tuning.

• Real-time RPM from 0 to 25,000 for rapid diagnostics
• Max RPM recall to spot intermittent overspeed events
• Programmable rev limit to protect the engine during tuning
• Selectable refresh rate (0.5s or 1s) to match test needs

Can it track service intervals and work hours for multiple machines?

Yes—this meter reports an unresettable total run time and a resettable job timer so you can track cumulative service hours and individual task durations. It can store two separate maintenance reminders so different machines or jobs can be monitored with a single device.

• Total (unresettable) time up to 6000 hours with 0.1h accuracy
• Resettable job timer for tracking separate engine use
• Dual maintenance reminders that flash and use red backlight alerts
• Stored times remain visible when engine is off

What engines and installations are supported?

The Timorn tachometer supports a wide variety of ignition systems and cylinder configurations for both 2-stroke and 4-stroke engines. Installation is non-invasive: wrap the included sensor wire around the spark plug lead and secure with the provided tie for inductive sensing—no cutting of wires needed.

• Compatible with 2-stroke and 4-stroke engines across many cylinder counts
• Works with common portable generators like GY6, EU2000, EU2200, EU3000
• Inductive pickup requires five wraps around the spark plug wire
• Useful on motorcycles, lawn mowers, compressors, outboards, tractors

How durable and power-efficient is this gauge for outdoor use?

Built for workshop and outdoor environments, the unit is IP67-rated so it resists dust and temporary immersion. The meter uses an internal battery with data memory so recorded hours and settings persist through battery changes, and it offers auto-sleep and adjustable backlight timeout to conserve power.

• IP67 waterproof rating for rugged outdoor use
• Data memory retains hours and settings after battery swap
• Auto sleep mode and selectable backlight time to save battery
• Simple swap battery replacement without losing stored data

Who this is for: The Timorn Small Engine Tachometer is aimed at DIY mechanics, maintenance technicians, landscapers, mariners, and small-farm operators who need a compact, accurate tool to monitor engine performance and service intervals. If you tune engines, maintain fleets of small equipment, or use portable power tools and generators, this unit provides straightforward RPM and hour tracking without complex wiring or bulky instrumentation.
