Simple Intuitive user Interface

The “SPM” series of self-contained electronic torque meters is built on a Digitool Solutions’ exclusive rotatable platform. These meters transform any large wrench or non-impact driver into a high-precision torque instrument. They feature a simple, intuitive user interface for torque preset of fastener installation specifications. Tri-colored visual indicators, an audible signal and a tactile vibration provide preset alerts at torque attainment. Built on a robust square-drive extension and Installed between the tool and the work, these meters are free of hand-hold position error that is typical of common torque wrenches.

Torque Measurement Accuracy Within ±1% of Setting

Two models, with 3/4in square drives covering 20 ft-lb to 600 ft-lb in two ranges, function in both CW and CCW directions while maintaining torque measurement accuracy within ±1% of setting from 10% to 100% of full scale. The meter can be used down to 4% of full-scale setting while retaining a +/-3% accuracy. With extra-precision torque sensing and higher resolution analog-to digital conversion, the SPM is intended for critical industrial, aerospace, laboratory and quality control applications. The nylon housing is robust enough for tough field use. A built-in rechargeable Li-Ion battery system provides 300-hours of continuous operation. A global 110-240VAC wall transformer is included for charging.

Each meter is compliance with ISO-6789-2003, ASME B107.28-2005 (Type 2) Standards and N.I.S.T. A certification of calibration can be provided if requested.
