Portable Digital Tachometer (Dual Contact/Non-Contact type)


Model CT500

  • Multi-function: One instrument combines Photo-tachometer (RPM) & Contact Tachometer (RPM & m/min).
  • Wide Measurement range from 15 RPM to 75,000 RPM.
  • The last measured value is automatically stored in memory when the 'measure' button is released.
  • High contrast LCD display with leading zero blanking gives the exact RPM.
  • The battery consumption is very low. In Non-measure mode i.e. the measure button is released (memory ON), the battery consumption is still lower.
  • This tachometer uses an advanced Micro Computer LSI Circuit with Quartz Crystal time base to give high accuracy and fast measurement.
  • A high intensity RED LED for photo- tachometer gives a visible low current consumption beam. Unlike a filament bulb, an LED has almost infinite life.
  • The use of a durable, strong ABS plastic housing assures maintenance free performance for many years. This housing fits comfortably in the palm of the user.
