Oxygen Sensors
At Process Analyser Systems UK we offer a range of specialised oxygen sensors tailored for diverse gas analysis applications. These sensors support trace and percent O₂ measurements in CO₂-rich environments, inert gases, and hydrocarbon streams. Models such as the A-2C, A-5, B-1, and Instatrace series deliver precise O₂ monitoring, including in acid gas backgrounds, with options for fast response and long life. PAS UK sensors are ideal for applications requiring reliable, accurate O₂ analysis in complex gas mixtures.
Available Oxygen Sensors
A-2C
Application: Used for trace O2 measurements in CO2 containing backgrounds (0.1-100% CO2) CO2 must be present
Notes: Use where acid gases are present (CO2, HCl, HCN, etc). CO2 must be present.
A-2CXL
Application: Specifically qualified A2C sensor to operate in XL model analyzers. Low range limit is 0-1 ppm
Notes: Use where acid gases are present (CO2, HCl, HCN, etc). CO2 must be present.
A-5
Application:Intermittent or continuous monitoring of percent O2 in gas mixtures containing 0-100% CO2. 90% response time in 45 seconds
Notes: Has more tolerance to exposure to air than A-3. No restrictions on CO2 concentration.
B-1
Application: General purpose percent oxygen analysis where fast response is desired (90% in less than 7 seconds)
Notes: Use B-3 or C-3 where longer life is required and response time is relatively unimportant. May be used to spot check flue gas.
B-1C
Application: General purpose percent oxygen analysis where fast response is desired (90% in less than 7 seconds)
B-2C
Application: General purpose trace O2 analysis for use in inert gas and hydrocarbon streams. Low range limit is 0-10 ppm
Notes: May be used in CO2 free gas streams containing highly mobile gases such as H2, He and ethylene.
B-2CXL
Application: Specifically qualified B-2C sensor to operate in XL model analysers. Low range limit is 0-1 ppm
Notes: May be used in CO2 free gas streams containing highly mobile gases such as H2, He and ethylene.
B-3
Application: Percent O2 analysis, best compromise between long life and fast response
Notes: May be used to spot check flue gas.
E-2
Application: Long life cell for use in model 3290 (for use in unattended air liquefaction nitrogen skids)
Notes: Has a 3 to 4 years expected life in air. Minimum range 0-1000 ppm.
Instatrace
Application: Special patented construction provides rapid recovery, during initial cell installation, to low ppm levels by reducing the recovery period from several hours to just minutes
Notes: Used for trace O2 analysis in inert gas and hydrocarbon streams.
Instatrace CO2
Application: Special patented construction provides rapid recovery, during initial cell installation, to low ppm levels by reducing the recovery period from several hours to just minutes
Instatrace XL
Application: Special patented construction provides rapid recovery, during initial cell installation, to low ppm levels by reducing the recovery period from several hours to just minutes
L-2C
Application: Used for general purpose trace O2 analysis in the 3000T analyser series
