I recently bought a Norbar NorTorque-60 wrench at Amazon Global Store for $108 (plus $6.50 import fees). This wrench covers the range of 12-60 N-m (10-45 lb-ft). The NorTorque tools are a little cheaper than the Norbar Pro line.
Accuracy of the NorTorque is very similar to the PRO version that Trav bought.
For my wrench:
Maximum observed error at low setting of 12.0 N-m is -0.25%
Maximum observed error at mid setting of 35.0 N-m is -1.7%
Maximum observed error at high setting of 60.0 N-m is +1.1%
For Trav's wrench:
Maximum observed error at low setting of 10.0 N-m is +0.70%
Maximum observed error at mid setting of 30.0 N-m is -1.8%
Maximum observed error at high setting of 50.0 N-m is -1.0%
The PRO version is designed to maintain calibration over a higher number of use cycles than the NorTorque. Setting N-m values on the NorTorque is easy and accurate, with resolution of 0.5 N-m. Setting lb-ft values accurately will require a little more patience and concentration and excellent eyesight. For my DIY use, I will be using the N-m values. If you prefer to work with ft-lb, and/or use a torque wrench 5-6 days per week, get the PRO version.
