•The Proto® Electronic Torque Meter is one of the world's first true all-in-one torque meters. The Proto Electronic Torque Meter provides the maximum flexibility in lab and production applications. This system meets a broad range of needs from demanding users and can eliminate the need for multiple electronic torque wrenches and testers. The system grows as the demands of the user grows. •Ideal for use in production (application of torque), quality control (verification of torque) and for the calibration and or verification of torque wrench accuracy (calibration labs and kit rooms). •Easy to learn and use. Anyone can be up and running in seconds. Unit designed with the user in mind. •Accuracy. Four to eight times more accurate than a conventional torque wrench or tester. •Accuracy to .5% with bench mounted transducers. •"Plug and play" torque transducers. Automatic set-up of transducers means user friendly operation and less down time. •Versatile all-in-one unit can be used as both an accurate torque wrench and as an accurate torque tool tester. No need to buy separate torque testers and electronic torque wrenches. •First peak of torque mode allows hand calibration of click type torque wrenches. •Memory for traceability. •Standard rechargeable 9 volt battery.
