A test equipment manufacturer has announced a new automatic contacting extensometer, which reportedly supports faster, more reliable and more precise materials testing.
Instron’s new machine, named AutoX 750, is said to have a high accuracy of +/- 1μm, with a maximum travel of 750mm and multiple knife edge options.
The AutoX 750 meets strain measurement specifications of ASTM E83, ISO 9513 and ISO 527-1. It also complies with ISO 6892-1 Method A and ASTM E8.
The data supplied by the new extensometer works in conjunction with Instron’s Bluehill 3 software, which records and stores the data.
The extensometer also claims to feature the simultaneous opening and closing of both arms with just one motor, a debris shield to protect it from damage and an ergonomic tensioner to adjust the gripping force of the measurement arms.
The automatic nature of the extensometer is said to allow the user to increase throughput while maintaining a high level of repeatability and accuracy throughout the duration of the test.
