1. OVERVIEW The Model T360U is a close derivative of the Model T360 CO 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 has an extra pneumatic port for the exhaust of the purge gas to the
GFC wheel.
Because the T360U is a close derivative of T360, the Model T360 Operation Manual
continues to be valid as the reference manual covering the details of the instrument’s
components and operation.
