2.2.6 Micro-Fuel Cell “Class”

Analytical Instruments manufactures Micro-Fuel Cells with a variety of

characteristics to give the best possible performance for any given sample
conditions. A few typical Micro-Fuel Cells are listed below with their typical
use and electrical specifications.

2.2.6.1 Class A-3 Cell

The class A-3 cell is for use in applications where it is exposed continu-

ously to carbon dioxide concentrations between 1 % and 100 % in the
sample gas.

Nominal output in air is 0.20 mA, and 90 % response time is 45 s.

Expected life in flue gas is 8 months.

2.2.6.2 Class A-5 Cell

The class A-5 cell is for use in applications where it is exposed intermit-

tently to carbon dioxide concentrations up to 100 % in the sample gas.

Nominal output in air is 0.19 mA, and 90 % response time is 45 s.

Expected life in flue gas is 8 months.
