##### Universal Torque Sensors

# Series R51

##### Universal Torque Sensors

A great solution for general bi-directional torque testing applications requiring different sample sizes. Three interchangeable chuck capacities and bit holder are available. The R51 has superb overload protection and is available in capacities from 10 ozFin to 100 lbFin (7 to 1,150 Ncm).

Requires a Mark-10 indicator, available separately.

- Member of the Plug & Test
^{®}family of interchangeable sensors and indicators - Outstanding overload protection
- Interchangeable chucks (order separately)
- NIST-traceable certificate of calibration with data is included. If the sensor is ordered with an indicator, a certificate for the set (indicator + sensor) can be supplied upon request, at no additional charge.
- Warranty: 3 years
