1、High Accuracy: This 3/4in torsion wrench is highly accurate, with an angle in the range of 30‑500N.M. The tolerance of accuracy in clockwise direction is ±2%, and the tolerance of accuracy in counterclockwise direction is ±2.5%. 2、Multifunctional: This 3/4in drive electronic torsion wrench is multifunctional with preset mode and 100 sets of data storage function, which can preset and save 6 sets of torsion and angle values. 3、Target Torsion Multi Alert: This electronic torsion wrench has an alert feature that warns you when you are approaching your target torsion, the electronic torsion wrench will beep periodically and the LED indicator will change from flashing green to a steady red light to let you know it's time to stop applying force. 4、Multiple Measurement Modes: This digital torsion wrench provides 4 real time torsion measurements in the N‑m, in‑lb, ft‑lb. kg‑cm range. It switches between peak hold mode and track mode. In track mode, the balancing force can be applied by changing the displayed value. In Peak mode, the generated torsion value is recorded so that you can check it at any time. 5、Safe And Reliable: This electronic scale torsion wrench has a locking mode to avoid accidental contact with the values. It also has an auto sleep mode that automatically goes to sleep mode after 2 minutes when you are not using it.
