Digital torque wrench eliminates the possibility of human error with a series of lights and alarms that immediately alert the user to torque readings that are “over or under” entered values. Easy to use, exceedingly accurate (plus or minus 1percent CW, plus or minus 2% CCW) and featuring a high contrast, backlit LCD screen display, users press only four buttons to operate the tool: power on/off; unit of measurement (ft./lbs., in./lbs., N-m); torque target up; and torque target down. Technicians can quickly switch among three types of measurement, eliminating the need to have three separate tools. The wrench boasts a non-slip grip, a rugged, durable housing, a 36-tooth gear and a lever-type ratchet to ease directional switching. Size: 1/2″ drive. Capacity: 20-250 ft./lb. Overall length: 25″. Estimated battery life: 110 hours.
