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.
K-TESTER series: the pinnacle of innovation
The K-TESTER is Kolver’s cutting-edge torque analyzer. Versatile and precise, it can be used with both static and rotary transducers (up to 4, simultaneously!), depending on the application.
The intuitive touchscreen interface provides instantaneous torque data and real-time torque graph visualization, while live PC connectivity enhances testing capabilities through our K-TorqueAnalyzer companion software, for in-depth joint analysis, tool calibration, and torque studies.
With high accuracy, support for up to 200 programs and advanced reporting, the K-TESTER offers unparalleled efficiency for diverse torque testing needs.
The same readout can later be used with other transducers, available separately.
Torque range: 0.44 - 885 lbf-in (up to 4,400 lbf-in on request)
Mini K series: versatility at a low price
K/S with integrated transducer
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.
Note: the K/S testers should be used in the clockwise direction only.
Torque range: 0.9 - 177 lbf-in
KeF with external static transducer
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
Ke/S with external rotary 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.
Note: the mini Ke/S testers should be used in the clockwise direction only. Torque range: 4.4 - 442.5 lbf-in
Our torque analyzer software is free and fully loaded for auditable laboratories and offers operator tracking, serial number tracking, easily searchable fully archivable database, pdf and excel report generation.
