Bolt Tension Monitors / Meters
Dakota NDT Bolt Tension Monitors and Bolt Tension Meters provide accurate, reliable measurement of bolt elongation, load, stress, and strain to help ensure fasteners remain within required safety standards and engineering specifications.
Using advanced ultrasonic bolt measurement technology, these precision instruments accurately calculate bolt stretch and tension in nanoseconds, delivering highly dependable results for critical bolted joint applications.
Unlike traditional torque measurement methods, ultrasonic bolt tension monitoring is unaffected by temperature, friction, lubrication, or resistance factors that can reduce accuracy. Dakota ultrasonic bolt tension gauges can measure elongation with exceptional precision up to 0.0001mm (0.00001 inch), making them ideal for safety-critical industries and high-performance bolting applications.
The Dakota BT1-DL and BT2-DL Bolt Tension Monitors feature fully customisable operator settings, including audible and visual pass/fail warning limits for individual readings or batch inspections. These advanced bolt load monitoring systems improve quality control, maintenance efficiency, and non-destructive testing (NDT) procedures across a wide range of industrial environments.
Widely used in wind turbine maintenance, bridge inspection, offshore oil and gas, heavy engineering, theme parks, construction, and structural monitoring, Dakota NDT bolt tension meters deliver accurate ultrasonic fastener measurement for demanding industrial and safety applications.

Dakota BT1-DL (Mini Max)
The BT1-DL formerly known as MINI-MAX v2.0 Ultrasonic Bolt Tension Monitor from Dakota NDT accurately measures the actual elongation produced by tightening a threaded fastener.
The MINI-MAX bolt tension monitor can measure the elongation very accurately in fasteners of virtually any material from 1/2 inch to 50 feet in length.
For longer lengths, see the Dakota MAX II Bolt Meter.
Dakota BT2-DL (Max II)
The Dakota NDT BT2-DL formerly known as MAX II Ultrasonic Bolt Tension Monitor / Meter is the latest gauge addition to our bolting products range.
It incorporates all of the great features of the MiniMax unit, with some added benefits in terms of features, hardware, speed, and length. The Dakota MAX II bolt meter very accurately measures fasteners up to 100 feet in length.
