The Dakota Ultrasonics TI-MINIMAX Bolt Tension Monitor Meter Z-182-0002 Extensometer is a state of the art instrument designed to measure elongation produced by tightening a threaded fastener. The Dakota Ultrasonics TI-MINIMAX Bolt Tension Monitor Meter Z-182-0002 Extensometer can measure the elongation very accurately in fasteners of virtually any material from 1/2 inch to 4 feet in length. The measurement is achieved by determining the change in the transit time of an ultrasonic shock wave along the length of the fastener as the fastener is tightened by any method. The on-board microcomputer automatically interprets this time measurement to display the time(nanoseconds), elongation, load, stress, or %strain from stretching a fastener.
The Dakota Ultrasonics MAX-II Ultrasonic Bolt Tension Monitor Z-197-0001 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 MAX-II Bolt Tension Monitor 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.
