Class

Application

Comments

A-1

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

Used for trace O2 measurements in CO2 containing backgrounds (0.1-100% CO2). CO2 must be present.

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

A-2CXL

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-5

Intermittent or continuous monitoring of percent O2 in gas mixtures containing 0-100% 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

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

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.

B-2CXL

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

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

May be used to spot check flue gas.

B-5

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

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 in 13 seconds. Expected life in air is 6 months.

B-7

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

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.

C-3

Percent O2 measurements where maximum cell life is desired (high O2 applications).

90% response time is 30 seconds. Expected life in air is 18 months.

C-5

Special application cell (non-standard) where long life is required; the C-5 has a factor of 3x the life of a C-3 cell.

Requires 3x the amplifier gain of the C-3. Expected life in air is 54 months.

C-5F

Special application cell (non-standard) where long life, in the presence of CO2, is required.

Requires higher amplifier gain than normal. 90% response time is 30 seconds. Expected life in air is 9 months.

C-6

Motion insensitive percent O2 measurements for use in hand held portable monitors.

Best cell for OEM safety applications.

InstaTrace

Special patented construction provides rapid recovery during initial cell installation; Low range limit is 0-10ppm.

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

InstaTrace CO2

Special patented construction provides rapid recovery during initial cell installation by reducing the recovery period from several hours to just minutes. Used for trace O2 measurements in CO2 containing backgrounds (0-100% CO2) in the 3000T analyzer series.

Use where acid gases are present (CO2, HCl, HCN, etc). CO2 must be present. The INSTA TRACE Micro-fuel Cell oxygen sensor is capable of measuring below 1 ppm of oxygen within 15 minutes of installation.

InstaTrace XL

Specially qualified sensor to operate in XL model analyzers with a low range limit of 0-1 ppm.

Used for trace O2 analysis in inert gas and hydrocarbon streams
