3/4" 400 ft-lb Electronic Portable Torque Meter SPM-4004

Self contained Torque meter ±1% Accuracy in Both CW & CCW Directions Simple Intuitive user Interface The “SPM” series of self-contained electronic torque meters are 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, innovative user interface for torque preset of fastener installation specifications. Tri-colored visual indicators, an audible signal, and a tactile vibration provides preset alerts at torque attainment. Built on a robust square-drive extension and installed between the tool and the component being tightened, these meters are free of hand-hold position error that is typical with common torque wrenches. Torque Accuracy Within ±1% of Setting Six models, with square-drives covering 24 “in-lb” to 600 “ft-lb” and 3 to 813 “Nm” with tools that function in both CW and CCW directions while maintaining torque measurement accuracy to within ±1% between 10% to 100% of full scale. The meter can be used down to 4% of full-scale setting while retaining ±3% accuracy. Furthermore, with the 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 glass filled nylon housing is strong enough for heavy industrial use. A built-in rechargeable Li-Ion battery system provides 300-hours of continuous operation. A global 110-240V AC wall transformer is included for charging. This meter is compliant with both ISO and ASME B107-28 (Type 1) Standards. A certificate of calibration with N.I.S.T. traceability is provided with each meter.
