The Digital Multi-Length Strain Gauge Set is used to yield precise physical measurements of strain in materials or structural components under load, relative displacements in structures, opening or closing of cracks, shrinkage of the concrete block during curing, and similar applications. The anodized aluminum alloy instrument frame adjusts for measuring at 2, 4, 6, 8, or 10in spacing (5, 10, 15, 20, 25cm for metric) of Punch Bar and Invar Master Bar used.
The Digital Multi-Length Strain Gauge Set has a digital indicator and is switchable to measure to 0.0001in or 0.001mm with a data output interface. Battery life is 5,000 hours.
The Storage Case includes slots for the Invar Master Bar for Strain Gauge and Punch Bar for Strain Gauge – both are required items of the Strain Gauge Set sold separately, and available in English or Metric models. Master Bar has stainless steel seat inserts to check gauge space settings. Punch Bar has one fixed point and one moveable point and is used to accurately locate the position of brass Inserts in the specimen.
