Proto® is expanding its lineup of Dial Electronic Wrenches with seven new SKU’s. Users now have a total of nine sizes to choose from, with torque ranges from 7.5 in-lbs. to 2000 ft-lbs. So whether it’s a small cap screw on a motorcycle engine cover, a large bolt on an oil rig, or anything in between, Proto® has a wrench that’s up to the task. The Stanley® Proto® Dial Electronic Torque Wrench design includes a durable chrome body (not painted) and a sturdy rotary bezel.  The electronic interface keypad is designed for ease of use and offers a number of advantages to users. Some key features include: Torsional strain gauge technology improves accuracy to +/-1% in BOTH directions (compared to 4% CW and 6% CCW on mechanical models). • Accuracy is valid from 10% to 100% of Full Scale (versus 20-100% for mechanical wrenches). • A fast sampling rate ensures the wrench will measure peak torque the moment it’s reached. • Torque measurements can be read in in-lb., ft-lbs., or N-m, simply by pressing a button. • Track and Peak Hold modes are standard on all models. (In Track Mode the wrench displays real-time torque; in Peak mode it holds the highest measured torque until released.) • A green light and a buzzer indicate when the target torque has been reached; a red light and an intermittent buzzer warn when the fastener has been over-torqued. These features are a great help when working in low light conditions. • The patented bezel rotates up to 359 degrees, so that the user can easily view the readout from any direction. The bezel is shrouded with metal walls to protect display. • The torsional strain gauge technology produces accurate torque reading regardless of where the load is applied on the handle. This is a real convenience where access limits the user to a certain hand position. The new wrenches are ergonomically designed for user comfort, and operate on standard 9-volt batteries. They are manufactured to meet or exceed ASME B107.28.
