The extensive Norbar torque wrench range can be divided into the following series:
TruTorque – The wrenches from the TruTorque series are easily adjustable and have a display on which the torque can be read (in Nm). The wrenches are bi-directional and have an accuracy of ± 3%. The torque wrenches have a comfortable handle and the torque setting can be easily secured. Capacities vary from 15 to 300 Nm.
Professional -The Professional Norbar torque wrenches are exact (±3%) and are directed at specific applications in the automotive or aviation industry. These tools have parts that resist all corrosive substances (such as skydrol) common in such environments, handles that provide excellent grip even in oily conditions and a locking mechanism, which prevents accidental adjustment of the wrench during operation. The ‘P’ types cannot be set by the user. Capacities from 1 to 200 Nm.
The 550 – 1500 (Nm) models have an “extension handle” to increase ease of use and a positive ‘click’ can be heard, seen and felt, when the desired torque is reached.
Industrial – The Industrial wrenches have the same technique as those included in the Professional series, but have a slightly higher capacity, ranging from 8 to 400 Nm. There is also a “P”-type (which cannot be set be the user) available in this series. There are extra long wrenches (3 AR to 6 AR) for heavy duty activities with setting ranging from 100 to 2000 Nm.
Slimline – These torque wrenches are suitable for applications in areas, where there is not much space due to their compact size. Very precise and reliable. Capacities from 1 to 20 Nm.
The wrenches are calibrated by means of Norbar testing instruments and Norbar reading instruments.
