Proto® Dial Electronic Torque Wrenches ft. lbs./inch lbs./newton meters
- Accuracy valid from 10% to 100% of full scale
- Large easy to read digits
- Patented rotary bezel. LCD and key pad rotate both ways, up to 359 degrees for easy viewing
- Torque target zone adjustable 1% to 10% indicates when the desired torque limit is approaching
– Yellow light indicates the low end of the zone
– Green light and buzzer sounds when the target is reached
– Red Light with intermittent buzzer indicates over-torqued - One button target torque setting
- Ergonomically designed for user comfort
- Operates on standard 9 volt battery
- Torsion drive strain gauge technology improves accuracy
– Users can pull on the handle anywhere and still maintain accuracy - Built on durable chrome body (not painted) with nylon-6 rotary bezel
- Rotary dial is shrouded with metal walls to protect display
- Peak, hold and track modes standard
- Fast sampling rate helps maintain high accuracy during torque applications
- Easy to use by production line or quality control inspector
