PM700 Process Oxygen Analysers

Paramagnetic oxygen analysers PM700

Paramagnetic oxygen analysers for high purity oxygen with full percent range capability.

Utilising the well proven magneto-dynamic (dumb bell) transducer, the PM700 offers the best in class of high performance oxygen analysis. These highly advanced instruments incorporate user-friendly software to provide accurate and reliable results. This paramagnetic analyzer is ideal for oxygen purity measurements with autoranging from 0.01% to 99.99%. The non-depleting sensor provides years of trouble free operation.

Available in four different configurations:

  • Panel mounted or bench mount oxygen analysers
  • NEMA 4X / IP66 waterproof and weatherproof oxygen analysis units
  • 19 in. rack mount


  • Industry : Process
  • Gas : Oxygen
  • Application : Industrial Gas, Medical Gas Analysis
  • Measurement range : Autoranging from 0.01 to 100% Oxygen
  • Technology : Paramagnetic
  • Response Time : 90% of reading (T90) less than 6 seconds
  • Explosive gas mixtures : Use the Ex-Proof Sensor Housing for explosive gas mixtures such as H2, Butane, CO, H2S
