The Tornado digital torque tester measures clockwise and anticlockwise torque up to 10 N.m. Portable and battery powered, the Tornado can measure "slip torque" and "bridge torque" on tamper-evident closures. Interpreting results is extremely easy as there are audible and visible indications of the settable "Pass" and "Fail" limits. Up to 500 results can be held in the on-board memory which can be down-loaded to a printer, computer or a Statistical Process Control system
