Specimen Verification
The GCTS RFG-100 Specimen Flatness Gauge is used for the final step of specimen preparation. It is designed to precisely measure the flatness of a specimen for strength testing. GCTS also offers an upgrade to the RCV-100 to meet ASTM D4543 specifications.
GCTS also offers Specimen Core Drills and Specimen End Grinders to fully prepare a cylindrical rock specimen for testing.
