2.2.6.3 Class B-1 Cell
The class B-1 cell is for use in applications where it is exposed to less
than 0.1 % of carbon dioxide, and where fast response is important.
Nominal output in air is 0.50 mA, and 90 % response time is 7 s.
Expected life in air is 8 months.
2.2.6.4 Class B-3 Cell
The class B-3 cell is for use in applications where a slightly longer
response time is acceptable in order to have a longer cell life.
Nominal output in air is 0.30 mA, and 90 % response time is 13 s.
Expected life in air is 12 months.
2.2.6.5 Class C-3 Cell
The class B-1 cell is for use in applications where it is exposed to less
than 0.1 % of carbon dioxide, and where a longer response time is accept-
able in order to have a longer cell life.
Nominal output in air is 0.20 mA, and 90 % response time is 30 s.
Expected life in air is 18 months.
2.2.6.6 Hydrogen and/or Helium Service
If the sample gas contains 10 % or more hydrogen and/or helium,
“clamp” cells are used. These Micro-Fuel cells are identified by the suffix
-C added to the cell class number.
