Epsilon Rock, Concrete and Asphalt Extensometers
AVERAGING AXIAL EXTENSOMETERS FOR LARGE COMPRESSION SAMPLES
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.
Designed for applications where tensile or compressive strength tests on small rock, concrete and other small compression samples is desired.
MINIATURE AVERAGING AXIAL EXTENSOMETERS
Designed for concrete and rock compression testing or for compression tests on other large samples.
EXTENSOMETERS FOR SIMPLE PERFORMANCE TESTING OF ASPHALT
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.
Designed to many of the needs for testing asphalt core samples in 4 and 6 inch diameters.
EXTENSOMETERS FOR CREEP COMPLIANCE AND TENSILE STRENGTH TESTING OF ASPHALT
Designed to meet many of the needs for testing asphalt core samples in 4 and 6 inch diameters.
EXTENSOMETERS FOR INDIRECT TENSILE TESTING OF ASPHALT
Designed for accurate measurement of small diametral strains such as those required to determine Poisson’s ratio of rock, concrete and asphalt samples.
