E-MED Electronic precision control is achieved by high performance servo motors with an accuracy of +/- 3%and a repeatability of +/- 2%. Using a patented gear box design, this series of tools produces continuously controlled torque. Compared with traditional hydraulic wrenches, tightening efficiency can be increased by 300%. WREN provide after-sales service all over the world, and already got the approved by TUV certificate.
