Introduction

The Model CGA 351 monitors the oxygen content of any clean and
dry gas stream. The analyzer can accurately measure oxygen levels
from 0.1 ppm to 100% O2, and can even measure oxygen content in
reducing gases. This is accomplished with a precision, temperaturecontrolled, zirconium oxide (zirconia) oxygen sensor.

**The standard CGA 351 analyzer is supplied in a pair of stainless steel,

Nema 4X/IP66 enclosures mounted side-by-side on a metal plate with a 40” flexible conduit connecting the two. This compact, wallmounted system includes the following components:**

• a sensor enclosure, which contains the oxygen sensor, sensor furnace, thermocouple, inlet port with needle valve, outlet port with flowmeter, and interconnecting cable(s), and
• an electronics enclosure, which contains the temperature control circuitry, output signal processing circuitry, digital display, user interface, and wiring terminal strips.

The CGA 351 analyzer is also available in optional enclosures. See Appendix C for more information.
