DT-207LR (LED) Tachometer

DT-207LRSeries DT-207LR (LED) Combination Contact/Non-Contact Laser Tachometers

The laser-enabled DT-207LR has precise RPM measurement up to 20 feet. The Series DT-207LR digital tachometers incorporate laser technology yet retain our hallmark rugged construction and reliable quality components. Units offer incredible value and versatility as they can operate in non-contact and contact applications. These instruments feature a field-upgrade-able contact adapter for linear rate measure, conveniently allowing both non-contact and contact measurements. Incorporating the precise laser technology and user-friendly functions as the DT-207LR tachometer, the DT- 207LR-S12 provides an exceptional accuracy in measuring speed and length via its 12” wheel. The larger wheel rotates more slowly than a standard 6” wheel, enabling reliable and safe registration of high speeds.

All Series 207LR units come standard with a NIST traceable calibration certificate. We’re confident you’ll agree that these fine units are the most advanced handheld tachometers on the market
