Accuracy
± 2.0 % full-scale of Standard Ranges (Cells 40 cm or smaller), based on
minimum ranges (e.g., 40 cm):
H
2
S: ± 0.5 PPM
COS: ± 2 PPM
MeSH: ± 1 PPM
± 5.0 % full-scale of Low Range option (White Cell, 81.2 cm) to a minimum
of:
H
2
S: ± 0.25 PPM
COS: ± 1 PPM
MeSH: ± 0.75 PPM
Accuracy is determined by comparing analyzer response to a known stan-
dard gas after a calibration has been performed.
Repeatability
± 2.0 % full-scale of Standard Ranges (including Column effects)
Calibration
Calibration gases in nitrogen or methane.
Linearity
± 2.0 % full-scale of Standard Ranges to a minimum of:
H
2
S: ± 0.25 PPM
COS: ± 1 PPM
MeSH: ± 0.75 PPM
Stability
Noise: 1.0 % of Standard Ranges (excluding cross-talk effects)
