Oxygen Gas Analyzer :
The Percentage Oxygen Gas Analyzers cover
the range 0.01% to 100% and provide continuous analysis
of oxygen in industrial gas streams. The
Percentage Oxygen Gas Analyzer are Panel Mounted
instruments with optional back stand can also be used for
Bench Top applications. The transducer is sealed electro
chemical fuel cell that generates signal in direct linear
porportion to the oxygen concentration in the sample stream.
Percentage Oxygen Gas Analyzer requires no periodic
maintenance like replacing electrodes or electrolytes and
can be calibrated using ambient air or standard samples.
The Output is available on a digital readout with a reslolution
of 0.1 % or 0.01% depending upon model. Recorder terminals
are provided on back panel.
Percentage Oxygen Gas Analyzer Series 4000 is available
in two measuring ranges and each range has option of two
flow configurations. Model 4000 and 4406 cover the range
30.0%. Models 4440 and 4446 cover the range 0-100.0 % and
are recommended where high percentage is to be monitored.
Models 4400 and 4440 are simple flow inlet instruments useful
for low pressure flows. However where sample is available
from pressurised sources and other special features are
required, models 4406 and 4446 are recommended; these have,
in addition, flow regulation, flow reading (rotameter) and
Oxygen Cell Isolation valves provided in the flow circuit
for the transducer. Model 4400A has built-in sensor in diffusion
mode for atmospheric monitoring; where Remote Diffusion
Sampling is required Model 4404 is recommended. All Models
have alarm set facility available on a ten turn direct reading
dial and the output is a one pole two way relay with potential
free NO, C, NC contacts brought out on the back panel.
