Magicalmai Inductive Hour Meter for Engines — 2-Pack Black, IP68 Waterproof, Epoxy-Sealed Runtime Counter

Magicalmai Inductive Hour Meter is a sealed, battery-powered run-time counter that records accumulated engine hours for generators, lawn mowers, ATVs and other gas engines.

Keeping accurate service intervals for small engines starts with knowing how long they have actually run. This compact, solid-state hour meter from Magicalmai uses an inductive wire connection and a long-life internal battery to display total run hours up to 9,999.9 with 0.1-hour resolution. Built for outdoor use, the meter is epoxy-sealed, rated IP68 for waterproofing, and delivered as a two-pack so you can track more than one machine or keep a spare on hand.

How does this hour meter attach to my engine and start counting?

Installation is straightforward: loop the included sensing wire around the spark plug wire and secure the meter to the engine or chassis using the supplied screws or the adhesive strips. The inductive sensor detects ignition pulses and increments the internal counter while the engine runs. No external power connection is required because the meter runs on a sealed internal battery that maintains the display when the engine is off.

• Connect wire around spark plug wire — no cutting or splicing.
• Mount with included screws or adhesive strips for flexible placement.
• Automatic counting triggered by ignition pulses; no manual start needed.
• Internal sealed battery preserves total hours and the LCD readout.

What durability features protect it outdoors and in harsh conditions?

The Magicalmai hour meter is manufactured with 100% epoxy encapsulation and an IP68 waterproof rating, making it resistant to water immersion, vibration, and dirt. The solid-state electronics and robust housing allow it to operate across a wide temperature range, and the low-profile design minimizes exposure to impacts. These qualities make it suitable for marine, off-road, and workshop environments where moisture and shock are concerns.

• Epoxy-encapsulated internals for moisture and shock resistance.
• IP68 rating for reliable outdoor and marine performance.
• Operating range from -30°C to 85°C for extreme climates.
• Compact, lightweight housing reduces snagging and damage risk.

What information does the display show and can it be reset?

The large LCD shows the total accumulated hours in 0.1-hour increments up to 9,999.9 hours, with an hourglass icon indicating active counting. The total is non-resettable to preserve an accurate service history. The meter’s clear digits remain visible whether the engine is on or off, making it easy to check service intervals at a glance.
