Models 71, 51, and 31 force / torque indicators are designed for use with Mark-10's Plug & Test™ remote force and torque sensors. All calibration and configuration data is saved within the sensors' smart connectors - not the Indicator - allowing for true interchangeability. Each sensor series is available in a range of capacities, from 0.25 to 10,000 IbF (1 N to 50 kN) full scale and from 10 ozFin to 5,000 IbFin (7 Ncm to 550 Nm) full scale.
