BMA INDUCTIVE HOUR METER
- Installation:Â Extremely simple; the sensor wire wraps around the spark plug wire 5+ times, requiring no cutting or complex wiring.
- Operation:Â Automatically senses engine ignition pulses to begin recording, typically displaying an hourglass icon while active.
- Power Source:Â Usually features an internal, non-replaceable battery with a long lifespan (often 10+ years or ~20,000+ hours).
- Display & Data:Â Features an LCD screen, often showing total accumulated runtime (non-resettable) up to 9,999.9 or 99,999 hours. Some models include resettable trip meters (TM1/TM2) for tracking specific maintenance intervals.
- Applications:Â Ideal for small 2-stroke or 4-stroke gasoline engines, including motorcycles, ATVs, snowmobiles, generators, and lawnmowers.
- Durability: Typically epoxy-encapsulated for protection against water, shock, and high heat (often up to 85°C).
- Extra Features:Â Many models also act as tachometers, displaying real-time engine RPM.
