The CDI 501-I-ETT Electronic Torque Tester has a 1/4 Inch Drive and can test between 5-50 In lbs or .5-5.6 Nm. Unlike a torque calibration system, which can be used to generate a torque wrench certification, the ETT is a portable, battery powered stand-alone torque tester. It can also be used on AC power. Its primary use is to check the accuracy of dial and click type torque wrenches and torque Screwdrivers to maintain their accuracy in between calibrations.
With the addition of a joint rate simulator, ETT can also check stall and clutch type pneumatic and electronic torque tools. The 1/4" drive electronic torque wrench tester should not be used with any impact or pulse type tools.
