The Dakota BT1-DL (Mini-Max) Ultrasonic Bolt Tension Monitor defines the state of the art in the measurement of the actual elongation produced by tightening a threaded fastener.

It can very accurately measure the elongation of fasteners of virtually any material from 1 inch to 4 feet in length.

The measurement is achieved by determining the change in the transit time of an ultrasonic wave along the length of the fastener as the fastener is tightened. The on-board microcomputer automatically interprets this time measurement to display the time (nanoseconds), elongation, load, stress, or % strain from stretching a fastener.
