Measurement of physical properties is important for the classification of products but more than this, it is often critical to for proper calculation and evaluation of performance data. At TRI Europe we are prepared to determine all essential properties employing state-of-the-art equipment including:

  • A high-precision, professional Wolf Messtechnik thickness gauge with 2-200 kPa measuring range
  • A 20 kPa, high-precision Schmidt geomembrane thickness gauge
  • A universal loading frame (odeometer-like) with replaceable presser foot. This rig allows the application of virtually any requested uniaxial load and measurement of thickness using a calibrated dial gauge.
  • Numerous calibrated balance scales with different capacities and minimum accuracy of not more than 0,01 g.
  • Characteristic opening size apparatus with full set of calibrated sieves and a proprietary composition of calibrated glass beads
