tachometer
Achieve sustained performance and extended service life through optimal engine speed adjustment
Adjusting engine RPM is essential for improving fuel efficiency and extending engine life.
With Oppama Kogyo's tachometer, non-contact, simple, and high-precision measurement is possible.
Simply bring it near the spark plug wire to activate auto-on, reducing maintenance burden. No battery replacement needed for extended life. Easily measure engine manufacturer-recommended RPM ranges.
Features of
Tachometer
Non-contact measurement possible
The non-contact measurement method used in the Otsuka Industries tachometer is the world's first.Simply bring the tachometer close to the spark plug wire to activate auto-on mode, enabling easy measurement.
