4.5.1. SETTING THE GAS MEASUREMENT MODE
If the switching valves software is activated, the T101 can be set to one of three gas
measurement modes:
H
2
S
The sample gas stream is stripped of any ambient SO
2
by a special
chemical scrubber, then passed through a catalytic converter that changes
the H
2
S present into SO
2
which is then measured using the UV
Fluorescence method
SO
2
The sample gas stream bypasses the SO
2
Scrubber and catalytic converter
allowing the only ambient SO
2
to be measured.
H
2
S – SO
2
The switching valve alternates the gas stream between the two paths at
regular intervals allowing the instrument to measure both gases.
To select one of these three measurement modes (see Section 10.3.2 for additional
details), press:
