APPLICATION

COMMENTS

A-1
oxygen sensor

C6689-A1

Ultra-fast response (90% in less than 4 seconds) in the percent oxygen region.

Use only when B-1 response time is insufficient.

A-2C
oxygen sensor

C6689-A2C

Used for trace O2 measurements in CO2 containing backgrounds (0.1- CO2). CO2 must be present.

Use where acid gases are present (CO2, HCl, HCN, etc). CO2 must be present.

A-2CXL
oxygen sensor

B74033-A2CXL

Specially qualified A2C sensor to operate in XL model analyzers. Low range limit is 0-1 ppm.

Use where acid gases are present (CO2, HCl, HCN, etc). CO2 must be present.

A-2Cl: Obsolete, use A-2C

A-3: Obsolete, use A-5

A-5
oxygen sensor

C6689-A5

Intermittent or continuous monitoring of percent O2 in gas mixtures containing 0- CO2. 90% response is time is 45 seconds.

Has more tolerance to exposure to air than A-3. No restrictions on CO2 concentration.

B-1
oxygen sensor

C6689-B1

General purpose percent oxygen analysis where fast response is desired (90% in less than 7 seconds).

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-2C
oxygen sensor

C6689-B2C

General purpose trace O2 analysis for use in inert gas and hydrocarbon streams. Low range limit is 0-10 ppm.

May be used in CO2 free gas streams containing highly mobile gases such as H2, He and ethylene.

INSTA TRACE
oxygen sensor

B71875

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. Low range limit is 0-10 ppm.

Used for trace O2 analysis in inert gas and hydrocarbon streams.

B-2CXL
oxygen sensor

C6689-B2CXL

Specially qualified B-2C sensor to operate in XL model analyzers. Low range limit is 0-1 ppm.

May be used in CO2 free gas streams containing highly mobile gases such as H2, He and ethylene.

B-3
oxygen sensor

C6689-B3

Percent O2 analysis, best compromise between long life and fast response.

May be used to spot check flue gas.

B-4C
oxygen sensor

C14613-B4C

Trace O2 cell specifically designed for the Model 317EXI.

Same performance as the B-2.

B-5
oxygen sensor

C45091-B5

Special application cell (non-standard) where long life and moderately fast response are required; B-5 has a factor of 3x the life of a B-3.

Requires 3x the amplifier gain of the B-3. Expected life is 36 months in air.

B-5F
oxygen sensor

C45091-B5F

Special application cell (non-standard) where long life and moderately fast response, in the presence of CO2, are required.

Uses Type F (acid electrolyte). Requires higher amplifier gain than normal. 90% response time is 13 seconds. Expected life in air is 6 months.

B-7
oxygen sensor

C45091-B7

Special application cell (non-standard) where fast response is required; the B-7 has a factor of 3x the life of a B-1 cell.

Requires 3x the amplifier gain of the B-1. Expected life in air is 24 months.

B-7F
oxygen sensor

C45091-B7F

Special application cell (non-standard) where moderate life and fast response, in the presence of CO2, are required.

Requires higher amplifier gain than normal. 90% response time is 7 seconds. Expected life in air is 3 months.
