Dakota Mini-Max Bolt Tension Monitor

The Dakota Ultrasonics Mini-Max bolt tension monitor can ultrasonically measure the actual elongation produced by tightening a threaded fastener. This bolt tension monitor allows you to effectively monitor your bolts during periodic shutdowns over the service life of the fastener and visually compare the unloaded and loaded waveforms. The Mini-Max can measure bolts 1/2″ up to 50 ft (15.24m). The square wave pulser is selectable in 100, 150 and 200 volts. It features a large 110 dB gain range and a resolution of ±0.00001 inch (0.0001 mm).
