Incompatible substances

  • Not suitable for measurements with oxygen.
  • Contact with strong oxidising agents (e.g. peroxides, chromates) can lead to fire hazard.
  • Mixing with nitrates or other oxidising agents (e.g. chlorates, perchlorates, liquid oxygen) can create an explosive compound.


  • Use under 0°C.
  • Less evaporation than water due to its lower vapour pressure.
  • Greater stability of the Packing Fluid level.
  • Improvement in the repeatability of measurement results.
  • Reduction in the required frequency of Packing Fluid level monitoring.
  • The gas remains dry.
  • In general, a lower chemical reactivity with water.
