LEOMAUNYX Mini Digital Tachometer & Hour Meter for Small Engines — Clip, Backlit Display, IPX68

LEOMAUNYX Digital Engine Tachometer & Hour Meter is a compact, inductive-equipped gauge that tracks RPM, logs running hours, and warns you when an engine exceeds a preset limit.

This handheld instrument combines a tachometer, hour meter and maintenance timer in one robust package designed for small gasoline engines. Lightweight and water-resistant, it connects via an inductive clip or by contact to give fast RPM readings and persistent runtime records. The clear backlit display, programmable alarm and removable battery make it a practical tool for mechanics, landscapers, marine users and DIYers who need precise engine monitoring without bulky equipment.

How accurately does it measure engine speed?

The LEOMAUNYX tachometer reads RPM using non-contact inductive sensing or a contact method, updating values every 0.5 seconds for near real-time feedback. It stores the maximum RPM from the last session so you can review peak performance after shutdown. The built-in RPM alarm uses a red backlight to signal overspeed events when you exceed the programmed threshold.

• Inductive sensing distance: 3–5 cm for safe non-contact measurement
• 0.5s refresh rate for fast RPM updates
• Displays MAX RPM from last run for diagnostic checks
• Programmable RPM alarm with red backlight warning

What runtime and maintenance tracking features are included?

This device records total operating hours (TOT) and individual job hours (JOB), while a service timer (SVC) reminds you when scheduled maintenance is due. Data memory preserves hour logs during battery replacement, so records remain intact between power cycles. Simple one-key reset and mode switching make it easy to manage multiple tasks or equipment pieces.

• TOT: cumulative engine hours for long-term tracking
• JOB: track hours per task or owner
• SVC: set maintenance reminders for oil changes or inspections
• Data memory retains records during battery swaps

How durable and portable is this gauge for field use?

Engineered with ABS housing and an IPX68 rating, the gauge withstands wet conditions and routine outdoor handling. At 86 g and compact dimensions (7.5 × 7 × 4.5 cm) it fits in a pocket or tool bag, and the detachable battery simplifies replacements in the field. The included alligator clip with induction wire and O-rings help secure the sensor to cables or spark plug leads for consistent readings.

• Compact: 7.5 × 7 × 4.5 cm and 86 g for easy portability
• Waterproof IPX68 suitable for damp environments
• Durable ABS body for everyday workshop use
• Comes with clip, induction wire, and multiple O-rings for mounting

How simple is it to operate and maintain?

Operation is straightforward: MODE and RST buttons switch functions and reset counters without menus or complicated setup. It supports two measurement methods (inductive non-contact or direct contact), and the unit runs on an easy-to-replace battery with built-in power detection to alert you to low power. Green backlight provides clear night viewing while red backlight warns on overspeed.

• One-key controls for fast mode changes and resets
• Two measurement modes: inductive and contact
• Battery power detection and removable battery design
• Green/readable backlight; red overspeed warning backlight

Who is this for: The LEOMAUNYX Digital Tachometer & Hour Meter suits hobbyists, lawncare professionals, small-engine mechanics, boat owners and anyone who needs compact, reliable RPM and runtime monitoring. It’s especially helpful when tracking maintenance intervals, preventing overspeeding, or logging hours across multiple machines where portability, waterproofing and quick readings matter.
