Measuring Range
Non – Contact: 1.00 – 99,999 rpm
Contact : 1.00 – 19,999 rpm
Combination Hand-Held Digital Tachometer combines the best features of both contact and non- contact models to accurately measure RPM, surface speed and length.
When using the non-contact mode,rotational speed (RPM) is measured using a visible beam of light. The CDT-2000HD can be up to 24 inches away from the small piece of reflective tape that is affixed to the rotating element. In the contact operating mode, the speed is sensed by directly contacting the rotating device using the cone tip or surface speed wheel supplied with the instrument.
