Torque tools should be tested and calibrated at least once a year, to guarantee that you are performing your bolted joint works in a safe and effective manner.
Because there is such a variety of torque wrenches and torque multipliers, the testing equipment (also called ‘torque testers) should be able to work with all of these torque tools. This, among other matters, means that the measuring instruments (torque transducers) and the reading instruments (which visualise a certain torque and compares it with other data) should be able to manage various capacities.
For being able to offer you a complete series of torque testing instruments, Laco works together with two torque tester manufacturers: Skidmore-Wilhelm and Norbar. Practically every torque tool can be checked and calibrated with the torque testing instruments of these two brands.
You can purchase or hire Norbar measuring and reading instruments at Laco.
