Instruments for measuring rotation frequency, rpm, surface speed and distance

 

CDT2000 Contact and Non Contact Tachometer with linear speed attachments

tachometer Combination Hand-Held Digital Tachometer combines the best features of both contact and noncontact 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.

Combined Contact and Non Contact Tachometer with LCD or LED display linear speed attachements

These models combine the best features found in both contact and non-contact tachometers for the accurate measurement of rpm, surface speed and length. The screw-in contact adapter makes it quick & easy to convert from non-contact to contact operation.

DT-105/7 Economy Direct Contact Tachometer with LCD or LED Display and speed attachements

DT-105A, DT-107A and DT-107A-12 contact tachometers accurately measure rotational and surface speed, as well as length. A built-in selector switch permits the user to display readings in a wide variety of engineering units. The DT-107A-12 includes a 12" circumference measuring wheel
