Electric Torque Wrench
These tools are primarily used anywhere accurate torque is required on a nut and bolt, or where a stubborn nut needs to be removed.
These planetary torque multiplier gearboxes have multiplication ratios up to 4000:1. The correct torque output is adjusted by controlling the voltage.
The tool has an internal computer that shuts off the voltage at a certain level that is adjusted by the operator of the tool. Because of the internal electronics, the Electric Torque Wrench can operate from 110 or 220 volts. It can adjust in an instant up to 253 volts. Since the tool is operated by electricity, there is a waterproof version of the electric torque wrench available.
