DT-207L
Tachometer

Hand-held tachometer for accurate contact measurement and non-contact measurement of revolution of engines or shafts as well as surface speed and length e.g. belts and conveyer belts

Tachometer with LED display and many selectable units

High quality hand-held tachometer for professional use

Special Features

  • Hand-held tachometer DT-207L for non-contact measurement of revolutions and contact measurement of revolutions, line speed and length with an adapter;
    the measurement is carried out, as long as the measuring key is pressed

Non-contact measurement of revolutions, using a laser beam and reflective tape

Contact measurement of revolutions, surface speed and length

  • For exact measurement of revolutions per minute, total revolutions, length and velocity with different metric and English units
  • 9 User selectable measuring units (rpm; m/min; ft/min; yd/min; in/min; m; in; ft; yd)
  • Tachometer DT-207L with large, red, easy to read LED display, recommended at adverse lighting conditions
  • Hand-held tachometer DT-207L with automatic and manual memory (MAX, MIN, last and 10 separate readings) for recall in display
  • Rugged aluminium housing with fixing for tripod (1/4-20 UNC thread)
  • Optionally available: Inspection Certificate 3.1 according EN 10204 with calibration report

Standard Features

  • Measuring distance up to 2 m
  • Easy to use
  • Certificate of Compliance with the order 2.1 according EN 10204 is included
