The GE-2500 diesel engine tachometer uses rotation speed of an alternator to measure engine rotation speed. With FFT calculation, this tachometer achieves reliable and stable measurement for both diesel and gasoline engines.

The OM-1500 is a compact type detector designed for measuring rotation speed of an alternator. It detects magnetic flux leakage from an alternator. It is used to combine with the GE-2500. (The OM-1200 can also be used with the GE-2500.)

It may not be measured depending on the engine and motor type. For more details, please contact your nearest distributor or send us an e-mail: overseas@ONO SOKKI.co.jp)
To use the GE-2500, the alternator and engine must be running in synch with each other. The measurement error may become large when the special kind of alternator is used or the belt between the alternator and engine is loose.
It can not be measured or a measurement error may become large depending on the structure of an alternator.
