Automatic Consolidation Testing System - ACONS

Related Standards: BS 1377-5 : 1990;ASTM D4235-04; AS 1289.6.6.1; XP PG4-090-1

VJ Tech take pride in simplifying procedures for all modern day laboratories, saving our clients time and money. The design and manufacture of our ACONS system achieves this once again.

The Automatic CONsolidation System is simple and easy to use, specifically designed to carry out the Oedometer test.

Automatic Consolidation Instrument (ACONS)


  • Large LED Graphic Display
  • Simple 16 key operation
  • Computer controlled operation - daisy chained to enable multiple tests to be run simultaneously and independently*
  • On board calibration and linearisation
  • No weights required
  • Fully automatic loading and unloading sequences*
  • Automatic load application can nearly halve test time*
  • Space saving - far smaller footprint than conventional dead weight system
    * When used with csOEDO software

VJT-csOEDO: Clisp Studio Oedometer


  • User defined data logging intervals
  • User defined loading & unloading increments
  • Automatic loading (subject to software)
  • On screen measurement of T50 & T90 values
  • Live Tabular display of logged and calculated data
  • Live Graphical display of logged and calculated data
  • User defined views/graphs/tables
  • Standard predefined presentation reports
  • Export of data to Excel & test script export and import
  • Customised reports (at additional cost)

You can use any of our Consolidation Cells; other manufacturers cells may be used with a special adaptor, which can be obtained from VJ Tech on request.

The ACONS supports all VJ Tech's range of data loggers either with LSCT or Digital Dial Gauge transducers for the measurement of sample settlement.

Consolidation Cells

Our fixed ring cells are made from corrosion-resistant material. The soil sample is placed on the lower porous disc with the cutter ring surrounding it. The cell ring them clamps down the cutter ring and the pressure pad (which has the upper porous disc attached to it) is placed over the sample. The whole of this assembly is enclosed within a Perspex cylinder.
