Standards & Uncertainties

Our laboratories are equipped with the most recent technologies and allow us to calibrate each instrument under its own specific operating conditions over the following ranges:

  • Gas calibrations within a range of 5 sccm to 6000 slpm, air or nitrogen equivalent
  • Liquid calibrations within a range of 0.378 kg/min to 1100 kg/min

To ensure the highest possible accuracy, our installations are equipped with the following calibration fluids:

  • Standard calibration gases include: Air, N2, Ar, He, H2 & CO2
  • Standard calibration fluids include: Water, MIL-C-7024 T2 and Oil (BP 2380)
