Photo (HT-3200 Contact Type Handheld Digital Tachometer)

The HT-3200 offers a Lo measurement range that starts from 0.5 r/min.
The circumferential ring and contact tip for rotation measurement can be stored in the back-side pocket of the main body.


  • 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.
