  • Capable of measurement from a low speed at 0.5 r/min (when low range selection) up to a high speed at 10,000 r/min (when high range selection).

  • A large-size display device (10.5-mm character height) is incorporated into the compact, lightweight device.

  • Built-in convenient memory function for easy confirmation of the measured results

  • Dual-purpose type—replacing the contact tip with the circumferential ring enables circumferential measurement

  • Equipped with a storage pocket for the circumferential ring

  • The latest measurement value continues to be displayed for approximately 30 seconds even after the power has been switched off.

  • Battery replacement time indicator is provided.

This is a handheld type tachometer for measurement and maintenance of rotation machineries. We provide four types of tachometer (contact, non-contact, contact and non-contact, and external sensor). Every type can be easily operated and measures the rotation precisely. They are used in the various applications for periodic maintenance of mechanical equipments and for hobby products etc.

*It is dangerous to measure rotating machinery at high speed by the contact type tachometer. Please use the goggle or the like with careful attention not to get involved to the rotating machinery or not to detach the contact tip from the main unit.
* Before affixing a reflective mark onto the measurement object, please make sure that the rotating shaft is completely stopped.
