DT-205LR – DT-207LR
Combination Contact and Non-Contact Tachometer

DT-205LR LCD Display with 6″ Circumference Measuring Wheel
DT-205LR-12 LCD Display with 12″ Circumference Measuring Wheel
DT-207LR LED Display with 6″ Circumference Measuring Wheel
DT-207LR-12 LED Display with 12″ Circumference Measuring Wheel
The DT-205LR & DT-207LR 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.
