Accredited ISO 17025 calibration certificate for these 3i Basic Force Indicator force tools is be available on request (for an extra charge). Why Calibrate?


The 3i digital force / torque indicator is designed to work with a wide range of Mark-10 remote force and torque sensors. With exclusive Plug & Test TM technology, all calibration and configuration data is saved within the sensor’s smart connector, not the indicator, allowing for true interchangeability. In addition, all sensors are fully compatible with other Mark-10 indicators.

Mark-10 Force/Torque indicator - i3: video presentation

The 3i shares its menu structure and most specifications with Series 3 digital force gauges. The sampling rate is 2,000 Hz, producing accurate results under a wide range of test conditions. A backlit graphic LCD displays large characters, and a menu is available to access the gauges’ features and configurable parameters. The display also features an analog load bar for graphical representation of applied load, as well as set point indicators for pass-fail testing. USB output is provided for data collection purposes.

The gauges include MESUR TM Lite data acquisition software. MESURTM Lite tabulates continuous or single point data. One-click export to Excel allows for further data manipulation.

This Mark-10 Indicator (model 3i) works with one of the Mark-10 interchangeable force and torque sensors through Plug & TestTM technology. For a complete gage, you can choose Mark-10 Digital Force Gauges Series 3, designed for tension and compression force testing in numerous applications from 0.12 lbF to 500 lbF (0.5 N to 2500 N).
