Description
The controlled potential electrolysis principle is applied on the
H2S sensor.
Three electrodes
installed in the electrolytic cell, which are
working electrode,
grounding electrode and comparison electrode. A polarizing voltage
is applied at the
same time. The electrolytic cell is isolated from outer part by
a membrane. the
sample gas passes through it and reaches to working electrode,
produce an
oxidation-reduction. A small current will output from the
sensor. This current
is proportional to the H2S gas Concentration.
Infrared ray method is used to detect CO2 during logging in
WELLSTAR. Following are the detail operationm instructions;
