Teledyne manual Overview, Model GFC7000EU Specifications

MODEL GFC7000EU CO ANALYZER WITH AUTO-REFERENCE

(Addendum to GFC7000E Manual PN 04584)

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 CO2 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.
