Oxygen Analysers and Monitors

SAT Systems make a range of oxygen analysers using several different sensor technologies including:

  • Electro-chemical
  • Fluorescence Quenching
  • Paramagnetic
  • Zirconia (Please contact us for more information & availability)

All our new range analysers have barometric pressure compensation as standard. This has improved the day to day stability of the instruments. Analysers such as the O2-lite, CO2000 MKIII and all of the Air-5 and SAT-5 units benefit from this technology so they don’t require frequent calibration.

The most popular oxygen analysers use electro-chemical sensors. Electro-chemical sensors are low cost and able to work under pressure when a direct partial pressure measurement is required. Electrochemical sensors have to be replaced as they deplete with use.

Our oxygen fluorescence quenching sensors, currently available in our SAT-5 range of equipment, offer many advantages including high resolution, excellent temperature stability, barometric pressure compensation and long life in excess of 5 years.

Paramagnetic sensors use the physical property of oxygen which makes it attracted by a magnet. The paramagnetic effect is affected by temperature so the sensor has to have temperature compensation built in. Paramagnetic oxygen sensors do not deplete with time like electro-chemical sensors, but they are much more expensive and cannot be used under pressure.

The Zirconia oxygen sensor uses a zirconium dioxide solid electrolyte in a current limiting circuit to measure oxygen. This sensor is particularly good at measuring low oxygen concentrations such as trace oxygen in nitrogen generators. The sensor is very stable and does not require periodic calibration. Please contact us for more information & availability.

Oxygen analysers are available in the SAT-5 & Air-5 range of products. We also have a range of portable units as detailed in the tabs below:
