RPM & temperature gauge, operating hours counter ‘keep-racing® III’, for 2-stroke & 4-stroke engines

New version 2026

HOURS COUNTER ---- Track how long the engine has been running (TOT); Record individual time periods (JOB) and maintenance intervals (SVC1, SVC2) for maintenance purposes so that you can be informed in good time; TOT and JOB time range: 0 to 999,999 hours, SVC1 and SVC2 time range: 0 to 250 hours.

RPM METER – Displays real-time RPM through different engine ignition patterns for 2- & 4-stroke engines to adjust the engine idle speed; alarm channel for RPM overshoot reminder; display of the highest RPM since engine start; RPM measurement range: 0–25,000 rpm, alarm range: 0–25,000 rpm.

TEMPERATURE GAUGE ---- Keep an eye on the current and maximum engine temperature at all times with a sensor; Reminder when temperature is exceeded for engine maintenance; Easy switching between Celsius and Fahrenheit; Temperature measurement and alarm range: -20 °C to +300 °C (-4 °F to +572 °F)

BACKLIGHT ---- The green backlight makes it easier to use at night or in dark places. You can set the backlight to ‘always on’, “off” or ‘automatic’ as required.

MISCELLANEOUS --- - Easy to install by sticking it to any suitable location; Single-cable connection design for motor signal detection with shortened or extended cable (cable length: approx. 68.8 inches); 2 operating modes for different usage habits; Good water resistance thanks to the overall housing design and rear O-ring; User data is retained after the display is switched off or the battery is replaced
