Torque testers

Controlling torque is vital part of a company's quality control process. Fasteners that are insufficiently torqued can vibrate loose, while excessive torque can strip threaded fasteners. Therefore, using a quality torque tester has become more important than ever, and Kolver can help guarantee that you're well-equipped, offering the following product families to cover all of your torque measuring needs. 


Mini Ke/S Series with External Transducer

The Mini Ke/S system consists of a torque readout and an external rotary transducer. By connecting a rotary torque transducer between an electric or pneumatic tool and an assembly application, you can monitor the real torque being applied from the tool to fastener or bolt.

It is possible to connect different transducers to the same torque reader by setting the proper Correction Factor (FATC).
A Mini Ke/S is the ideal torque-auditing tool for testing the actual torque being applied on the assembly application.
Torque range: 4.4 - 442.5 lbf-in


Mini K/S Series – Portable Torque Testers

Our most compact and cost-effective option, the MINI K/S Torque Testers feature a built-in transducer. These easy-to-use torque testers are ideal for checking all power tools up to 20 Nm. The small size, weight and portability of MINI K/S make them ideal for checking torque tools on the production floor regularly to ensure the tools are always calibrated.
Torque range: 0.9 - 177 lbf-in


Mini KEF series

Similar to our Mini KS series but using external transducer elements that are interchangeable based on torque needs.
Torque range: 0.4 - 885.1 lbf-in


K Series – Advanced Torque Testers

The K Series Torque Testers feature a built-in transducer and can also be connected to an external transducer. They collect, store and eventually download torque measures for a complete analysis of the tool and/or the joint.
Torque range: 0.4 - 177 lbf-in


Our torque analyzer software is free and compatible with all series except for the K series and is fully loaded for auditable laboratories and offers operator tracking, serial number tracking, easily searchable fully archivable database, pdf and excel report generation.
