SAT Systems make a range of oxygen analysers using several different sensor technologies including:
- Electro-chemical
- Fluorescence Quenching
- Paramagnetic
Electro-chemical sensors are low cost but require periodic replacement as they deplete in proportion to the oxygen concentration they are exposed to. The majority of electro-chemical oxygen sensors use a small amount of lead for the sensor anode and a mild caustic electrolyte to generate current proportional to oxygen concentration.
Our fluorescence quenching oxygen sensors offer many advantages including high resolution, excellent temperature stability and long life in excess of 5 years. This sensor technology is available as an option in most of our analysers.
Paramagnetic oxygen sensors use the fairly unique property of oxygen that causes it to be attracted to a magnetic field. There are several methods of detecting the paramagnetism of oxygen, the magneto-dynamic method is used in the SAT-5 paramagnetic analyser. This detection method is largely unaffected by the composition of the background gas.
All our gas analysers have barometric pressure and temperature compensation to improve their day to day stability.
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:
