DI-1M Impact Tool Torque Tester
Click images to enlarge.
DI-1M torque testers are perfectly suited for on-the-spot calibration of impact drivers and air tools, but will calibrate any type of power driver. These fast response units give a digital readout of peak value in either clockwise or counterclockwise direction and also indicate the number of blows for a selected time period from 0.1 to 9.9 seconds. These instruments have an accuracy of ±0.5%, ±1 LSD and lbf-in/lbf-ft, kgf-cm/kgf-m, or N-cm/N-m units are selectable. USB output, auto zero reset, auto shutoff and low battery indicator complete the set of features. It is powered by an internal NiCad battery or the included AC adapter.

DI-1M Impact Tool Torque Tester with flange mount sensorPeak, Real Time and Peak Down modes are selectable.
Peak mode captures the peak torque achieved during a test. PEAK reading will not change until a higher value is measured.
Real Time mode displays the real time transient torque value.
Peak down captures the critical first peak value and will not change even if a higher value is subsequently measured.

Use the 800 internal memory for peak data recall or USB download for analysis by Imada data acquisition software SW-1SV-USB.

The DI-1M is supplied with the remote sensor, display unit, cable and AC adapter/charger.

Calibrate your own air tools and impact wrenches and save down time.

The readings displayed may vary from the actual torque that a tool applies to a thread joint, because testers cannot always duplicate actual joint characteristics. Verify the torque output of the tool being used on the actual assembly, when critical assemblies are involved.
