Designed primarily for compressive strength tests on rock, concrete and other large compression samples, this model measures axial strain on opposite sides of the test specimen, and the output is an average of the two readings. Gauge lengths from 1 to ...
Designed for concrete and rock compression testing or for compression tests on other large samples. This model may be used simultaneously with the Model 3542RA axial extensometers.
2 mm to 12...
Designed for accurate measurement of small diametral strains such as those required to determine Poisson’s ratio of rock, concrete and asphalt samples. The units are designed to be used in conjunction with the Model 3542RA axial averaging extensometer....
Designed to many of the needs for testing asphalt core samples in 4 and 6 inch diameters. The unit meets test method requirements for strain measurement developed under the U.S. Federal Highways SHRP program.

100 mm and 150 mm
Designed for measuring axial displacements in the simple performance tests prescribed by NCHRP Report 465, and determining dynamic modulus of hot mix asphalt per AASHTO TP062.
With gauge lengths of 1 and 2 inches (25 and 50 mm) and measuring ranges of 0.050 and 0.100 inches (1.2 and 2.5 mm), the Model 3442RA1 was designed for applications where tensile or compressive strength tests on small rock, concrete and other small com...
