Sample supply
The sample supply line must be heat-traced and/or insulated to keep the gas above dew
point. Check your sample data for required temperature.
Sample inlet connection on the analyzer is identified with a tag-plate.
The sample connection on the analyzer is for 1/8”OD tubing. Tubing size to the process
may require a different tube size, this should be determined taking into account process
pressure, sample line length and acceptable lag time.
