Model GFC7000T Carbon Dioxide Analyzer

1. OVERVIEW

The Model GFC 7000T is a close derivative of the Model GFC 7000TA CO2 Analyzer. The main differences are as follows.

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 rear panel is different. There is an extra pneumatic port for the exhaust of the purge gas to the GFC wheel. Also, there are relay alarm outputs available on the rear panel.

Refer to the main manual (i.e. GFC 7000TA) that is shipped with your instrument for details of the instrument’s components and operation. Any differences between this instrument and what is described in the GFC 7000TA, will be described in this Addendum to the manual.
