The Iron Roughneck Torque Tester (IRTT) is used for torque wrench calibration that is engineered to emulate the specific geometric and material properties of your joints. This likeness allows the IRTT to measure the torque delivered by an Iron Roughneck in situ: the IRTT is placed within the jaws and is loaded just like a joint connection.
Since a direct torque measurement is captured by the IRTT (not derived or estimated), it removes additional calculations, correlations or guess work. The IRTT directly measures the make-up torque that is being delivered to your joint connections.
Measurements captured by the IRTT will allow an operator to adjust the Iron Roughneck set point to maximize the accuracy of the make-up torque delivered.
