2.6 Electrochemical Cell
The TS4000H uses electrochemical cells with three electrodes and a sensor identification
board (Figure 3). This design provides the most stable and accurate gas detector possible.
NOTE:
The oxygen deficiency assembly contains only two electrodes.
Gas diffusing into the electrochemical cell reacts at the sensing electrode by reduction or
oxidation depending on the type of sensor being used. The counter electrode acts to balance
the reaction at the sensing electrode.

NOTE:
The oxygen sensor does not have an identification board. Nonetheless, the TS4000H
will automatically configure a fully functional oxygen cell.
NOTE:
For electrochemical cell shelf life information, consult the manufacturer’s
documentation.
