This item adopts the microcomputer (CPU) technique and junction laser technique for one instrument which combines Photo Tach (RPM) and Contact Tach (RPM, m/min).


Features:
1. Adopting advanced technologies to achieve contact or non-contact measurement of rotation speed and line speed.
2. Speed sensor with groove measures speed and length of wire, cable and rope conveniently.
3. Automatically store max value, min value and the last measurement value.
4. Contact accessory and photoelectric accessory can be converted mutually at any time to achieve multi-purpose use.
5. Automatically prompt when the voltage of power supply is lower than the specified value.
6. Large LCD screen for clear reading.
7. Wide measurement range and high resolution.
