The Norbar ProTronic Plus 9 Screwdriver features a 360 progressive LED ring for precise visual feedback. There is also a large LCD screen with a bright backlight, the numbers become larger and bolder during active torque for optimal viewing. Four alert modes (LCD, progressive LED, audible and tactile) provide excellent feedback in all working conditions. It has five easily selectable torque units (Nm, lbf.ft, lbf.in, dNm, kg.cm and kg.m (200Nm and above)). The ability to programme up to 10 pre-sets saves time in setting up frequently occurring applications. A wide range of advanced features (cycle counter, customisable sleep timer, language selection, auto torque calculation for torque adaptors, calibration alerts, battery level indication, and numerous alert mode customisations) allow the user to tailor the tool to their work preferences. Torque THEN Angle mode gives the user the ability to conveniently apply an angle to a fastener directly after achieving a torque target without the need to remove the torque wrench from the application. Power interruption technology helps to prevent loss of work and continuity if the wrench is impacted. A patent-pending, built-in calibration factor feature allows different head lengths to be easily accommodated. Fitted with a comfortable handle that provides a secure grip. Includes a T-handle for comfort when higher torque levels are required. The battery cap has been designed to prevent accidental loss. Supplied with a storage case and a traceable 'Calibration Certificate' allowing end-users to adhere to more stringent quality control processes.
