(Click image for a larger view) | This tiny and portable RPM meter and hour meter unit is chip controlled, fully programmable, and is suitable for both two and four stroke engines: one product fits all engines. It keeps in memory the max RPM and the time the engine has been running: both values are resettable. Its two small batteries last for years before needing to be replaced. A strong velcro for fixing is included. |
