Sample gas inlet conditions
The sample gas must be non-corrosive, non-flammable and non-
toxic. The utility unit has one gas path.
Sample gas pressure
p
abs
= 70 to 105 kPa (0.7 to 1.05 bar)
Test gas pressure
p
abs
≤
200 kPa (2 bar)
Note
If gas pressures > 250 kPa are expected, a suitable external
pressure reducer must be connected upstream.
Sample gas flow rate
• 70 l/h with SCC-S
• 100 l/h with SCC-C and SCC-F
Sample gas inlet temperature
10 to 50 °C
Note
The relevant data in the gas analyzer data sheets must be
considered as well for the sample handling components.
Gas connections
The gas connections are PVDF fittings for DN 4 / 6 mm tube.
Connecting the gas lines
• Use gas lines made from material that is suited to the
measuring task.
• Connect the gas lines to the gas inlet and outlet fittings on
the rear panel.
