A torque tester is used as a quality control device to test or calibrate torque-controlled tools. This includes electronic torque wrenches, click torque wrenches, dial torque wrenches, electric screwdrivers, air screwdrivers, pulse tools, cordless screwdrivers, nutrunners, and torque screwdrivers. Verifying that these tools are operating according to their specifications helps ensure the assembly process runs efficiently while reducing errors.

Today’s advanced torque testers include the ability to measure in clockwise and counter-clockwise directions, and potentially convert to engineering units (such as in·oz, in·lb, ft·lb, N·m, cN·m, kgf·cm, gf·cm, kgf·fm).

Torque is defined as a vector quantity which refers to any force which causes rotation. Torque testers measure properties such as torsional strength and stiffness and are used in quality control of various fields including medical devices, metals, and aerospace.

By definition, torque meter is a type of transducer, specifically a torque transducer that converts a torque measurement (reaction, dynamic or rotary) into another physical variable, in this case, into an electrical signal that can be measured, converted and standardized. As the torque applied to the sensor increases, the electrical output signal changes proportionally (torque detector).

Modern torque meters typically combine a transducer and digital display. The digital display reads signals from the transducer, translating it into torque values for display on screen. A transducer (also called strain gauge or stress sensor) typically made of metal whose resistance varies in response to applied forces; its output converts this change in resistance into electrical current that can then be translated into torque measurements using algorithms.

Highly Accurate Torque Meters From Cedar Japan:

Since 1971 Cedar is known for its accuracy in products and unique tools for torque management in the world and they have actively developed “what is not in the world”.

Cedar torque meters or torque testers are known in the world for high accuracy. They implement their own unique method of torque measurement and are regarded as the best torque meters in the world. Most Screw driver manufacturers in the world trust Cedar for testing their tools.
That’s not all, even the Research and development centers rely on torque meters from Cedar.

Cedar makes all kinds of torque testers, be it for your Electric Tools, Pneumatic Tools, Pulse Tools, Impact Tools, Compact Tools, Cordless Screwdrivers, Nut Runners, Wrenches etc.

The Torque meters come with digital display and you can also export the data or link with PC in some of the testers. Most of them come with features such as peak data hold, auto shut down, auto reset etc.

They also have unique Torque Meters for torque wrenches and impact tools and even pulse tools.

Special Torque meters are there for Screw inspection (Slip Torque Tester) which is a patented equipment and Rotation Friction torque.
