EXCECAR Digital Tachometer Hour Meter — IPX68 Waterproof Inductive RPM Gauge, Replaceable Battery, 0–18,000 RPM

EXCECAR Digital Tachometer Hour Meter is a compact, waterproof inductive tachometer that records RPM up to 18,000 and tracks engine hours with a visual RPM alarm for over-rev protection.

This compact instrument combines accurate RPM measurement and hour logging into a rugged, user-focused package. Built for motorcycles, lawn equipment, chainsaws, ATVs, generators and small marine engines, it uses an inductive pickup for safe, non-invasive sensing and stores settings through battery changes. Its IPX68 rating and replaceable battery make it suitable for wet working environments, while the programmable alarm and quick refresh rate provide immediate feedback to protect the engine and schedule maintenance.

How accurate and responsive is the RPM and hour tracking?

The EXCECAR tachometer measures engine speed from 0 to 18,000 RPM with a stated precision of ±10 RPM and logs runtime from 0 to 9,999.9 hours at 0.1-hour resolution. A fast 0.5-second refresh rate ensures readings stay current for tuning and diagnostics.

• RPM range: 0–18,000 RPM with ±10 RPM accuracy
• Hour meter range: 0–9,999.9 hours, 0.1-hour increments
• Refresh interval: 0.5 seconds for near-real-time readout

What safety and alert features help prevent engine damage?

You can set a programmable RPM alarm that immediately changes the display backlight from green to red when the engine exceeds the threshold. This clear visual cue helps you notice over-rev situations at a glance, while the smart sleep mode conserves battery when no signal is detected.

• Customizable RPM alarm with red backlight warning
• Default green backlight for normal operation and low-light visibility
• Automatic sleep after 2 minutes without signal to save battery

How durable and serviceable is the unit for outdoor use?

The housing is rated IPX68 for water resistance, making the unit suitable for exposure to wet conditions common in marine, landscaping and off-road environments. The battery is user-replaceable and the internal memory retains settings and accumulated hours during battery changes.

• IPX68 waterproof rating for robust outdoor performance
• Replaceable battery with low-power detection and memory retention
• Reset option (press M and S for 5 seconds) for clearing settings if needed

How simple is installation and what’s included in the kit?

Installation uses the included inductive sensing wire with an alligator clip that clamps to the spark plug wire—no direct electrical connections are required. A universal bracket secures the meter to tubes or frames, and the kit includes o-rings and a user manual so you can mount and start measuring quickly.

• Inductive clamp-on sensor wire (2.2 m) for safe, non-invasive installation
• Mounting bracket that fits tubular frames and handlebars
• Included accessories: sensing wire, three o-rings, and user manual

Who is this for: The EXCECAR Digital Tachometer Hour Meter is aimed at owners and technicians of small gasoline engines who need reliable RPM data and runtime logs for routine maintenance and performance tuning. It’s well suited to motorcyclists, landscapers, small-engine mechanics, ATV/UTV riders, boaters with outboard motors, and anyone who needs a compact, rugged tachometer with an easy installation and a visible over-rev alert. If you want a precise, weather-resistant gauge that preserves settings through battery changes and warns you visually at set RPMs, this unit is a practical, cost-effective choice.
