Combination Contact and Non-Contact Digital Tachometer
The CHECK-LINE CDT-2000HD Combination Portable 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 rotating device using one of the contact adapters supplied with the instrument.

The CDT-2000HD's rugged construction, portability and outstanding features make It an ideal choice for maintenance personnel, machine operators or others in a wide variety of machinery and material handling applications.

A non-contact only version, the CDT-1000HD, is also available. Click here for data sheet.
