tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. The device usually displays the revolutions per minute (RPM) on a calibrated analogue dial or a digital display.

DT-2236A Digital Photo/Contact Tachometer from Tecpel is an ideal instrument for measurement of rotational speed at rotating surfaces, rolls, wheels... The user can choose the contact measuring mode with direct contact to the surface of the rotating part or the non-contact mode (optical mode). The optical measurement needs small reflecting types for remitting the signal to the instrument.

DT-2236A from Tecpel comes with the following properties:

  • Optical measurement with reflecting tape stripe (rpm).
  • Contact measurement with conical adaptor (rpm).
  • Contact speed measurement with surface wheel (m/min).
  • ABS- plastic housing.
  • 5-digit LCD-display (turns automatically to the site of measuring mode).
  • Min- max- peak- hold.
