Laser Tachometer and Counter





  The TA110 Laser Tachometer and counter can be used to measure and test the number of rotations per minute (RPM) or total number of rotations or events on any spinning shaft, pulley, wheel, drive belt, fan, or other rotating objects in general, safely, accurately and easily due to its unique ergonomic design. Numerous application uses can be found in industrial, automotive, heavy duty, HVAC, agricultural and aviation maintenance sectors.

  Wide measuring range: 1 to 99,999 RPM or count, 2" to 20" reading distance, Min/max memory recall, backlit display, <0.3 sec response time, count function and auto power off.

Simple and easy to use

  • Simply attach a small piece of reflective tape to the shaft or rotating part, aim the laser beam to the reflective mark and read the RPM or revolutions count on the large display.
  • Maximum, minimum and last reading are automatically saved into the internal memory of the instrument, and can be recalled at any time
  • Bright and powerful laser optical system allows for easy targeting of rotating shaft, wheel, etc., even in bright daylight.
  • Measurement can be obtained from safe and comfortable distances from 2" to 200"
  • The large 5 digits digital display allows measurements of up to 99,999 RPM without need to switch scales or multiply readings.
