Compressometer-Extensometer – Digital Gauge
The combined and unbounded compressometer-extensometer conveniently tests concrete cylinders. The apparatus contains a third yoke located halfway between the two compressometer yokes and attached to the specimen at two diametrically opposite points. Additionally, a hinged middle yoke permits rotation of the two segments of the yoke in the horizontal plane. One indicator gives deformation readings, while the other furnished for the compressometer section. The unit measures changes in length and diameter. It also comes with 2 digital gauges with a range of 0.25″ and minimum graduations of 0.0001″.
