The Norbar Pro Adjustable Dual Scale Torque Handle has been factory calibrated to ±3%. A newly designed mechanism ensures the accuracy is retained for longer. The secure push/pull locking mechanism is quick and intuitive to use and prevents accidental adjustment. There is also a large scale window and long scale length for great visibility and accurate setting. The ergonomic handle features a high proportion of soft-feel, high grip material. Both the handle material and lens resist all chemicals in common automotive, industrial and aviation use. Supplied with a Calibration Certificate, which meets the requirements of ISO 6789-2:2017.
