  • Universal Flexural Sets for testing beams with the center and third-point loading. This set meets specific ASTM and AASHTO standards in testing the flexural strength of concrete beams.
  • 2in Cube Test Set include lower pedestal and upper platen assembly to outfit machines for testing compressive strength of smaller concrete cubes and cylinders.
  • 6in Cube Test Sets include a spacer, lower platen, and upper platen assembly for compression testing of 6in (152mm) concrete cubes.
  • Cylinder Splitting Sets are used to determine the splitting tensile strength of concrete cylinders.
  • Masonry Test Sets are designed to test the compressive strength of 8 and 12in (203 and 305mm) wide concrete masonry units and prisms.
  • 4in Spacers adjust vertical working clearance in the load frame opening to test samples in varying sizes.
  • 3x6in Cylinder Test Sets come with spacer and upper platen assembly, and outfit the machines to perform concrete strength testing on 3x6in (76x152mm) cylinder specimens.
  • Compression Machine Mounting Stands holds and elevates the 250 and 300 Series Compression Machines to a comfortable working height.
  • Printer Accessory for Compression Machines for models equipped with the Pro-Plus Controllers prints test reports and other data; a factory-installed computer chip ensures it functions with the Pro-Plus controller.
  • Able Cable® for Pro Controller Compression Machines to transfer data from units with Pro and Pro-Plus Controller to user’s computer.
  • Compressometers come in two sizes, 6x12in or 4x8in, with models that have digital, mechanical dial, or analog dial indicators. They measure the average deformation and strain of concrete cylinders during compression testing to determine the modulus of elasticity.
  • Compressometers/Extensometers are similar to Compressometers, but with a third center yoke to measure horizontal extension to also determine Poisson’s ratio, these units also come with digital, mechanical, or analog dial indicators. They fit standard 4x8in or 6x12in concrete cylinders.
  • Perpendicularity Verification Devices (PVD’s) are new tools to verify proper perpendicular alignment of concrete cylinders during compressive strength testing. The latest revisions to ASTM C39 require verification that alignment is within ±0.5° of vertical for each specimen tested when using Unbonded Caps.
  • Piston Over-Extension Limit Switches prevents over-extension of a hydraulic ram, offering increased safety, and minimized operator error.
