Dakota Ultrasonics Ultrasonic Bolt Tension Monitor - Extensometer

Transducers sold Separately

The Dakota Ultrasonics BT2-DL (MAX-II) Ultrasonic Bolt Tension Meter Z-197-0001 / Z-197-0002 is designed for precision measurement of fasteners up to 100 ft / 30 m in length. It incorporates all of the great features of the original MiniMax unit, with improved features, hardware, speed, and range. The MAX II is designed for use in a wide range of industrial and lab applications.

The Dakota Ultrasonics BT2-DL (MAX-II) Ultrasonic Bolt Tension Meter Z-197-0001 / Z-197-0002 enables you to accurately monitor bolt tension ultrasonically measuring the elongation (change in length) of your bolts. It enables you to re-visit your bolts in certain intervals and monitor the quality of your bolt connections over time.

The new "Auto Correlation" feature that helps you to optimize your transducer placement. Together with the large QVGA sunlight readable color display and the calibration function, it is very easy to use without the steep learning curves associated with other models
