The Geotest standard load frame is offered in capacities of 34,000 lb (150kN); 300,000 lb (1233kN); 350,000 lb (1556kN); 450,000 lb (2000kN); 675,000 lb (3000kN) and 1,125,000 lb (5000kN). For testing to meet the stringent ACI 363 recommendations, we offer a 4 column high stability frame in capacities of 450,000 lb (2000kN); 675,000 lb (3000kN); and 1,125,000 lb (5000kN). Piston is ground and lapped with 3 element packing used. Every Geotest compression machine comes with full fragment guards.


The Cybertronic digital readout is the most advanced digital now being offered. This can be retrofitted to any make load frame.

  • 24 bit high resolution
  • Stores up to 600 complete tests
  • Large graphic display with high resolution 320x240 pixel
  • RS232 connection to printer and/or PC with optional software fully complient to ASTM, BS, UNI, EN standards
  • Can monitor up to 3 different load frames
  • 6 languages available
  • Selectable measuring ranges (lb, psi, kN, kg/cm2, ton, mpa, N/mm2
  • Pace (load) rate display selectable in lb/s, psi/s, kN/s, kg/cm2, kg/s, mpa/s, N/mm2/s
  • Easy calibration through PC keyboard
  • Peak hold lock in
  • Digital retains a memory of the frequently used specimens: i.e., area, weight, specific gravity, etc., but can add personalization for specimens with irregular shapes
  • Display shows date, time, applied load and pace rate
