Compression Testing Machine, Fully Automatic Servo-Controlled

Servo-controlled compression frame that holds a programmed pace rate from 0.1 kN/s, with a dual-stage pump, live on-screen graph and auto stop on specimen failure. Supplied 250 kN to 5000 kN.

Typical applications

  • Compressive strength of concrete cubes and cylinders
  • Flexural strength of concrete beams, with the attachment
  • Modulus of elasticity, with the attachment
  • Splitting tensile strength, with the attachment
  • Compressive strength of cement mortar

Worth knowing before you order

A power-supply condition comes attached to this machine and it is a warranty term, not a suggestion: the manufacturer requires a 3 kVA three-phase servo-controlled stabiliser, and states that the warranty is void for damage caused by voltage fluctuation. Price the stabiliser into the order. This is a different machine from the digital 2000 kN compression frame also listed here, and the difference is the pace rate: this one is servo-driven and controllable from 0.1 kN/s, the digital machine from 1 kN/s. If you are testing low-strength or small specimens, or closing out EN 12390-4, the slower controllable rate is the reason to choose this one. The PC software and all three test attachments are quoted separately — they are not in the base machine.

Site preparation required

This instrument needs site work before delivery — typically a level grouted foundation, a dedicated power supply, and in some cases drainage or extraction. We issue the foundation drawing and utility schedule with the quotation so the civil work runs in parallel with the lead time.

Support available

  • Installation & commissioning
  • Calibration
  • Operator training
  • Annual maintenance contract
  • Spares & consumables

Calibration is arranged through NABL-accredited laboratories under the relevant scope. We state the scope and the certificate number on the quotation — see what accreditation actually covers.
