CTAS-BTMT Series Mechanical Wrench Calibration System

About the CTAS-BTMT Series Mechanical Wrench Calibration System

CTAS-BTMT Series have a system accuracy of 0.5% indicated reading for top 90% of tester range. This torque tester is designed to provide multiple torque ranges with one display. It is well suited for hand or power tool validation/certification.

These instruments are available with 2, 3 or 4 internal transducers, to a maximum of 750 Lbf/ft (imperial) or 1016Nm (metric) and also include a transducer port for connecting an external transducer for ranges over 750 Lbf/ft (imperial) or 1016Nm (metric) capacity. This system is available in various configurations and can be custom built to meet your requirements.

Multiple torque ranges, 2, 3, 4, 5 or more transducers with one display. This unit can provide all the torque transducers required in one tool room or calibration lab. Low cost, high quality, ease of use and with the ability to add data management features with the addition of software makes the CTAS-BTMT testers indispensable.

Rundown Fixtures

1/4” and 3/8” rundown fixtures (up to 1000 Lbf/in, 112Nm) are included, 1/2”, 3/4” and larger rundown kits are available but they are optional and priced separately.

CTAS BTMT Series Desktop Torque Testers (with Display)

CTAS BTMT Series Desktop Torque Testers with display can be built with the transducers listed below. The external transducer port can support any size/capacity transducer that we manufacture - from 10 Ozf/in to 50,000 Lbf/ft (imperial) 0Nm to 67,790Nm (metric). External transducers include the cable.


The CTAS-BTMTE transducers are mounted in a housing that is designed with through holes for mounting to a bench or a mounting plate. There are two standard sizes; one small housing for all transducers up to 250 Lbf/ft (imperial) or 338Nm (metric) and the large housing for transducers up to 2000 Lbf/ft (imperial) or 2711Nm (metric).

Our stationary transducers are supplied with internal square drives; 1/4”, 3/8”, 1/2”, 3/4” and 1” depending on capacity. Various rundown fixtures are available that are designed to fit in the internal square drive providing a means of testing power tools. Our transducers are manufactured from stainless steel, precision machined, strain gaged and thoroughly.
