Hydrogen Sensor (Optional)
Accuracy
H
2
: ± 2.0 % full-scale of standard ranges.
Based on a full-scale of 0–10 % H
2
in a Scot Contactor
Overhead application, where the sensor is in a temperature-
controlled Oven.
Cross-Talk
± 1.3 % of H
2
full-scale. This is the RMS error in the reading due to CO
2
,
H
2
O, and pressure effects.
Cross-talk of CO
2
is 0.75 %, H
2
O is 0.5 %, and pressure is 1 % of the H
2
full-scale.
Temperature Drift
1 % of customer full-scale over a 15 °C temperature change
24-Hour Drift
1 % of customer full-scale
Carbon Dioxide Sensor (Optional)
Accuracy
CO
2
: ± 5.0% full-scale of standard ranges.
Based on a full-scale of 5 % CO
2
in pipeline application, where
the sensor is in a temperature-controlled Oven.
Cross-Talk
No significant cross-talk from water, H
2
S, or hydrocarbons onto the
CO
2
measurement.
Temperature Drift
1 % of customer full-scale over a 15 °C temperature change
24-Hour Zero Drift
1 % of customer full-scale
