The FT-2500 is an advanced tachometer which measures the rotational speed by the FFT calculation. The rotational speed is calculated from the frequency signal of light, magnetism, vibration or sound.

The CT-6700 is a digital engine tachometer that measures the revolution speed of gasoline, diesel engines, and motors (EV/HEV) equipped on electric vehicles or hybrid electric vehicles or general rotating bodies. This compact tachometer supports 10 kinds of sensors with different usages and purposes including ignition pulse detector, gasoline and diesel engine rotation detector, and magneto-electric rotation detector. We are now able to measure engine rotation speed by ECU crank signal even when it is difficult to mount a detector on an actual vehicle.
