Simple, Cost Effective Torque Wrench Testing.

The importance of keeping your torque tools in peak calibration condition is well established and the method that many businesses use to achieve this is to use a third party calibration service. However, how much more convenient would it be to perform calibration checks in-house? Wrenches could be checked more frequently, immediately if a problem is suspected, and wrenches would not need to leave site unnecessarily.

The main reasons that more companies do not perform calibration checks on their own wrenches are the cost of testers and fears over the complexity of the testing equipment. Norbar’s new ‘TruCheck’ torque wrench testers aim to sweep aside these concerns. Both testers are very cost effective being significantly cheaper than most similar products on the market and the basic version of the TruCheck particularly is very simple to use.

The product comes in two versions: there is a basic version, simply called ‘TruCheck’ and a version with greater functionality called ‘TruCheck Plus’.

TruCheck

One of the concerns in putting a torque tester into an environment where people are not calibration specialists is that incorrect selections will be made with the potential of incorrect tool setting and consequently joint failure. Norbar’s solution is to remove all choices from the operator. The TruCheck is for click type torque wrenches and comes with a single measurement unit (N.m or lbf.ft).There is only one button on the device and that is to zero the display. Operation is simplicity itself and it is virtually impossible to go wrong!

TruCheck has an accuracy of +/-1% of reading over its operating range of 10 to 350 N.m or 25 to 250 lbf.ft and comes with a traceable calibration certificate.

TruCheck instruments are supplied as standard with a traceable calibration certificate for the clockwise direction. As an option, a traceable calibration certificate for the counter clockwise direction can be supplied.Also, as an option, UKAS calibration certificates from Norbar’s laboratory can be supplied.

TruCheck Plus

Accepting that some customers require more flexibility than the basic TruCheck, the ‘Plus’ adds a comprehensive range of features.With three modes of operation the TruCheck Plus is suitable for click wrenches, dial and electronic wrenches and in ‘track’ mode will continuously monitor the torque signal. There are three torque units - N.m, lbf.ft and lbf.in.

TruCheck Plus also has a user selectable ‘limit’ feature. The operator sets the target torque and tolerance and the instrument will calculate whether the reading is within tolerance and indicate the result by illuminating one of three coloured LEDs: orange = Low, green = OK, red = High.

Finally,TruCheck Plus has an RS-232 output and comes complete with an RS-232 cable.The reading, measurement unit and limit status (Low, OK or High) are output via RS-232.
