Timorn Small Engine Digital Tachometer & Hour Meter — IP67, 0–25,000 RPM, Programmable Rev Limiter

The Timorn Small Engine Tachometer is a compact digital RPM and hour meter that measures engine speed up to 25,000 RPM, logs total and job run time, and includes a programmable rev limiter plus service reminders.

This compact, IP67-rated gauge combines a digital tachometer and hour meter into one tool for technicians, landscapers, boat owners, and powersports riders who need fast, clear engine diagnostics. It reads engine rotations via an inductive pickup wrapped around the spark plug lead, stores total hours and two separate job timers, and recalls maximum RPM so you can spot abnormal operation quickly.

How does the Timorn tachometer show RPM and peak readings?

When installed around the ignition wire, the inductive sensor translates spark pulses into a live digital RPM readout and stores the highest value recorded for review. You can choose refresh speeds to balance responsiveness and stability.

• Real-time rpm display from 0 to 25,000
• Max rpm recall function to capture spikes
• Selectable refresh rate: 0.5s or 1s
• Inductive pickup requires five loops of wire for accurate sensing

Can this device track engine hours and job time for maintenance?

Yes — it functions as an unresettable total hour meter plus two separate resettable job timers, so you can monitor cumulative engine life and individual work sessions with the same unit. The display retains total hours even when the engine is off.

• Total running time range up to 6,000 hours, with 0.1-hour accuracy
• Two resettable job timers to separate equipment use or tasks
• Stored data persists through battery replacement thanks to memory function
• Clear numeric readout for quick service planning

What maintenance and safety features does it provide?

The tachometer includes a programmable rev limiter and a maintenance reminder that highlights when scheduled service is due, helping you avoid over-revving and missed maintenance windows. Visual alerts use a red backlight and flashing icon to draw attention.

• Adjustable rev limiter to help protect the engine from overspeed
• Service reminder with red backlight and flashing icon
• Auto sleep and configurable backlight timeout to conserve battery
• IP67 waterproof rating for damp or outdoor environments

Which engines and vehicles are compatible with this tachometer?

The Timorn meter supports a wide variety of small engine ignition types and cylinder configurations, covering many consumer and commercial machines. It is suitable for marine outboards, generators, motorcycles, lawn equipment, and more when the pickup is installed correctly.

• Works with 2-stroke and 4-stroke engines, multiple cylinder counts
• Compatible with common generator models and powersports engines (e.g., GY6, EU series)
• Simple installation on spark plug wire — no engine tear-down required
• Small format fits dashboards, instrument panels, or toolkits

Who is this for: The Timorn Small Engine Tachometer is aimed at mechanics, fleet managers, DIY tuners, landscapers, boaters, and any owner of small gasoline engines who wants a reliable, portable instrument for monitoring RPM, tracking service intervals, and logging run time. Its combination of a rev limiter, dual job timers, and waterproof build makes it a practical diagnostic and maintenance companion for field work, repair shops, and weekend projects.
