Extensometer for rock, concrete, and asphalt Epsilon Technology
Model 3542RA Averaging Axial Extensometers
Designed for compressive strength tests on rock, concrete and other large compression samples, the 3542RA measures axial strain on opposite sides of the test specimen, and the output is an average of the two readings. Gage lengths from 1 to 8 inches (25 to 200 mm) and measuring ranges from .050 to .250 inches (1.2 to 6 mm) are available.
