Digital Torque Meter (DTM) fits between the tool and socket to provide an easy-to-read torque display with a flash memory card that stores the date, time, and torque measurement for each bolt tightened. This information can be downloaded for reporting and quality assurance. The DTM21 reads a torque range of 620-1590 ft-lb. and is compatible with select wrenches.
The TONE DTM21EF digital torque meter fits between the tool and socket and provides a clear torque readout during tightening. A flash memory card stores the date, time, and torque measurement for each tightened bolt, and the data can be downloaded for reporting and quality assurance. It also supports clockwise and counterclockwise measurement and rotational capacity testing.
