The Digital Torque Tester is similar in appearance to the spring Torque Tester. However, this model features a digital readout and covers the entire testing range from 0 to 100 inch lbs. torque, for both application and removal. Additional features include tenths of an inch lb. resolution for greater accuracy, 30-second peak-hold to allow time for manual recording. Operates on one 9V battery or 110V power adapter.
