Dakota Ultrasonics Max II Bolt Tension Monitor
The Max II Ultrasonic Bolt Tension Monitor is the latest gauge addition to our bolting products. It incorporates all of the great features of the MiniMax unit with some added benefits in terms of features, hardware, speed and length. Max II very accurately measures fasteners up to 100 feet in length and sports our very best effort to date in terms of overall performance / power!
