Digital tachometer TKRT 10
Digital tachometer TKRT 10
The SKF TKRT 10 is a fast and accurate tachometer utilizing laser or contact to measure rotational and linear speeds. Equipped with a laser and a range of contact adapters, it is a versatile instrument and suits many different applications.
  • Wide speed measurement range: up to 99 999 r/min for laser measurement and 20 000 r/min using contact adapters
  • Measurement modes include; rotational speed, total revolutions, frequency, surface speed and length in both metric and imperial units
  • Laser can be used for safe and quick, non-contact rotational speed measurements at distances up to 0.5 m (20 in.)
  • Large back-lit LCD display enables easy reading in almost all light conditions
  • Angular range of ±45° to target helps facilitate easy measuring
  • Up to 10 readings can be stored for later reference
  • Compact design; one–hand operated instrument
  • Supplied in carrying case for protection and portability
