MODEL GFC7000EU CO ANALYZER WITH AUTO-REFERENCE

(Addendum to GFC7000E Manual PN 04584)

05134 Rev -

2

OVERVIEW

The model GFC7000EU is a close derivative of the Model GFC7000E CO Analyzer.
The optical bench is longer (14 m), making the instrument more sensitive at low CO

2

levels. The instrument has a user selectable full scale range of 0-100 PPB to 0-100 PPM
of CO2.
The instrument does not come equipped with a sample flow rate sensor. Hence, disregard
any reference to the flow sensor in the users manual.

Because the GFC7000EU is a close derivative of GFC7000E, the Model GFC7000E
Instruction Manual continues to be valid as the reference manual covering the details of
the instrument’s components. Only the sections of the manual that are different between
the GFC7000E and a GFC7000EU are listed in this addendum.

3.1.2. Pneumatic Connections

This section is similar to the one in the manual, with the following exception. The
extra port labeled “From Purge” is the exhaust port for the for the purge gas. The
gas needs to exhausted with a gas line not more than 10 meters long.

In addition, the GFC7000EU uses a different sample pressure sensor than the
GFC7000E. The GFc7000EU pressure sensor is rated for oxygen service. The part
number is listed in the appendix – spare parts.
