Dakota BT2-DL Benchtop Bolt Tension Monitor
The Dakota BT2-DL is a high-precision benchtop Bolt Tension Monitor designed to measure bolt tension, elongation, load, and stress using advanced ultrasonic technology. Unlike standard torque methods, the BT2-DL provides accuracy within ±0.00001 inches (0.0001 mm) for fasteners up to 100 feet in length.
