Automatic Oedometer Systems (ACONS Pro)

The Automatic Oedometer Systems – ACONS Pro allows you to carry out a complete consolidation test, without operator intervention, reducing testing time by up to 50%.

The ACONS Pro utilises a stepper motor, eliminating the need for weights, or a compressed air supply.

Our latest electronics on the Automatic Oedometer Systems allow for rapid application of target loads, with the flexibility to adjust PID for a variety of samples, ranging from stiff to soft soils covering all your testing needs.

Two Load Frame Options Available:

  • 15kN
  • 50kN
  • Compact design (small footprint)
  • Utilises a stepper motor, eliminating the need for weights, or a compressed air supply
  • Rapid application of target loads
  • Built-in logger allowing high-speed sensor data conversion (24-bit, up to 5000 samples/s)
  • Flexibility to adjust PID for a variety of samples, ranging from stiff to soft soils
  • Auto engage function to easily apply seating load
  • Upgradable to perform other tests such as CRS, SWCC and Triaxial
  • Standalone Use via Touchscreen display with data export to PC
  • Built-in live data table and graphs
  • Built-in auto protection for mechanical limits & sensor limits
  • Multiple Units can be controlled from a single PC via a LAN or Ethernet/USB hub
  • USB or Ethernet connectivity for PC Control
