Resonance Test Gauge (RTG-1)
Fast digital lab testing system...
Get results in just seconds!
The Resonance Test Gauge [RTG-1] system is typically used to measure the dynamic Young’s modulus (E), shear modulus (G) and Poisson’s ratio (ν) of asphalt, concrete, rock, masonry, carbon and other cylinder, beam, and core-shaped specimens. This system meets the ASTM C215 standard for resonance testing of concrete for dynamic properties and freeze-thaw durability testing (ASTM C666). A sample spreadsheet [+] for all moduli calculations for longitudinal, flexural and torsional tests is included in this package.
The RTG-1 system must be used with a Windows 7-10 device running Olson Instruments' RTG software. The computer or tablet is supplied by the user.
Hands-on training classes are available for all of our NDT test method systems and platforms is available at our Wheat Ridge, Colorado (USA) location, which is a suburb located approximately 15 minutes northwest of downtown Denver. Training may be available at your location by one of our agents by special arrangement.
