1000HDX
Instron introduces its 1000HDX Universal Testing Machine that features a dual test space for tension, compression, bend, shear, and flexure testing on high-strength materials. The machine is ideal for testing materials for the metal, fastener, and construction markets, including rebar, wire, strip, tube, plate and structural steel, as well as concrete. Unit is available with two different crosshead configurations: hydraulically-actuated open front design for increased productivity and operator safety; and manually-operated closed pocket design when budget constraints are a primary concern. Instron digital control electronics provide automatic recognition and calibration of transducers, while the Windows-based testing software provides ease of operation and flexibility. Accuracy is provided by load cell system and zeroing capability.
