BBTO Inductive Hour Meter Kit for Gas Engines — 2-Pack Black, Waterproof LCD Hours & RPM

Keep track of maintenance intervals and total run hours on a wide range of gas-powered equipment with this waterproof, epoxy-encased hour meter set from BBTO. The package includes two inductive hour counters with wires and mounting screws, a bright LCD that displays hours and RPM, and a rugged housing designed to resist vibration, moisture, and heat up to 85°C (185°F). Because it senses ignition pulses rather than drawing battery power, installation is straightforward and well suited for outdoor, marine, and powersports gear.

How does the inductive hour meter record engine hours?

The meter senses ignition pulses from the spark plug wire and converts those pulses into accumulated run time and RPM readings. It requires no internal battery because it draws power directly from the engine’s ignition signals, and the LCD flashes during operation to confirm detection.

• Senses ignition pulses via the included inductive wire
• Displays total hours up to 9999.9 and RPM up to 99,999
• Operates without a battery; powered by the engine’s ignition system
• Standby life better than 20,000 hours

Is the meter durable enough for outdoor and marine use?

Yes — the BBTO hour meter is built from impact-resistant ABS with an epoxy-encapsulated casing to seal electronics against moisture and vibration. It’s rated to withstand temperatures up to 85°C (185°F), making it suitable for lawn equipment, snowmobiles, boats, and other high-vibration or wet environments.

• Waterproof and shock-resistant epoxy encapsulation
• ABS housing resists impacts and UV exposure
• High-temperature tolerance up to 85°C (185°F)
• Suitable for marine and off-road conditions

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

Installation is quick: loop the inductive wire around the spark plug lead, secure the meter with the supplied screws or zip ties, and route the wire away from hot or moving parts. The kit contains everything needed for two meters so you can monitor multiple engines or keep a spare ready.

• Includes 2 meters, 2 inductive wires, and 4 mounting screws
• No cutting of wiring or additional power source required
• Mount with screws or zip ties; wire clamps to spark plug cable
• Visible, backlit LCD for easy in-field readings

What specific measurements and limits should I expect?

The BBTO unit records cumulative engine run time up to 9999.9 hours and can display RPM values up to 99,999. The screen flashes when the engine is running so you can instantly tell that pulses are being detected; it is intended for small gas engines and ignition systems compatible with inductive sensing.

• Hour readout: up to 9999.9 hours
• RPM readout: up to 99,999
• Flashing LCD during operation for activity confirmation
• Designed for small gas engines (generators, mowers, bikes, ATVs, boats)

Who this is for: The BBTO 2-piece inductive hour meter set is ideal for homeowners, small-shop mechanics, fleet operators, and recreation enthusiasts who need a reliable, low-maintenance way to track engine hours across multiple machines. If you manage preventive maintenance schedules for lawn mowers, generators, dirt bikes, ATVs, snowmobiles, or marine outboards and want a compact, waterproof counter that installs without complex wiring, this kit provides a practical and economical solution.
