Model: Ono Sokki

Handheld type digital engine tachometer to be designed for dedicated r/min measurement of 4-cycle diesel engines. R/min direct reading measurement is available only by clamping a CP-044 detector (sold separately) to a fuel injection pipe.

Both analog (switchable between analog and monitor output) and pulse outputs are provided; enabling to use analog output for data recording (monitor output for sensor waveform checking or analysis input signal of FFT analyzer), and to use pulse output for tracking analysis signal of FFT analyzer.
