Product Introduction
The working principle of non consumable oxygen sensors is Coulomb method, in which the oxygen in the sample gas is reduced in the electrochemical cell. Like traditional electrochemical oxygen cells, the electrodes in this type of cell are not consumed, so they do not undergo chemical changes when measuring oxygen. Therefore, there is no need to regularly replace or repair sensors.
Product parameters
Non consumable oxygen sensor
Features:
• Used in conjunction with the Moisture.IQ series analyzer to measure oxygen concentration in gases from trace to percentage levels
When used in low range applications for ultra pure gases, the sensitivity is less than 5 ppb
Sensors can be used for waterproof and dustproof enclosures indoors/outdoors
• Compatible with acidic gas applications without the need for gas scrubbing equipment
No need for regular replacement or repair of sensors
The intrinsic safety option can be used in hazardous areas
Optional VCR connectors can improve system cleanliness and leak integrity
Application fields:
petrochemical
• Purity of olefins
• Natural gas production
• Purity monitoring oxygen sensors for argon, hydrogen, nitrogen, and helium gases
O2 content in the heat treatment furnace
