Response time Related to the sampling time selected.
Typical for a full scale step change and
5 minutes between two consecutive
samples: one sampling cycle for 90%
response and two sampling cycles for
100% response

Sample inlet 0.07 bar (1psig) min., 4 bar (57.2 psig)
pressure max. An internal regulator reduces
pressure from 4 bar (57.2 psig) to
1 bar (14.3 psig)
Sample flow Flow rate of 300 mL/min is recom-
range mended. Minimum and maximum
allowed are 100 mL/min and
500 mL/min, respectively
