Fig. 2-5 Carbon Monoxide Range
Hydrogen Sulphide, 0 – 100 ppm
(CSM mode only)
The Hydrogen Sulphide range measures on the ppm scale.
The digital display resolves to 1 ppm H2S. The analogue
bar graph follows in 4 ppm steps. Above 100 ppm, EEEE
is displayed. Figure 2-6 illustrates the Hydrogen Sulphide
display.
The Hydrogen Sulphide sensor is subject to the effect of
pressure transients and should be operated at normal
atmospheric pressure conditions. The sensor has a normal
operating life of two years.
