Key Features and Benefits

  • Oxygen will be detected but will not be quantified. For accurate oxygen analysis an external oxygen sensor is required.
  • Internally purged diaphragm valves ensure no air contamination and the lowest detection limits possible.
  • Ultra-high purity fittings and regulators.
  • Fused silica lined tubing ensures repeatability and maintains sample integrity.
