CD-3A
Carbon Dioxide Analyzer
Introduction
The Model CD-3A Carbon Dioxide Analyzer provides a continuous
and accurate measurement of gases containing up to 15% CO2.
The Model CD-3A has the rapid response necessary for breath-bybreath analysis during respiration. It is also ideal for laboratory
applications requiring high accuracy and sensitivity.
Features:
•
•
•
•
•
Wide range—0 to 15% CO2
High accuracy and sensitivity
Rapid response—ideal for accurate breath-by breath
measurement
End Tidal CO2 Display
Microprocessor controlled—reliable, low maintenance
operation
The Gold Standard in
laboratory carbon dioxide
analysis for over 20 years,
worldwide.
Model P-61B Sensor
Capabilities
A complete Model CD-3A consists of a sensor, readout/control unit, and
cable. When the sample gas is passed through the sensor, a voltage
that is a function of the carbon dioxide concentration of the gas is
generated. This voltage is fed to the readout/control unit via a
connecting cable.
The optional R-1 (Single Channel) or R-2 (Dual Channel) Flow Control
Unit can be used to draw the sample through the sensor. Each flow
control unit contains a pump, a needle valve, and a flowmeter for each
channel. Other gas handling equipment can be used if preferred.

R-1/R-2
FLOW CONTROL UNIT
The AEI Technologies R-1 and R-2 Flow Controllers are commonly used as an
integral part of any gas measurement system. Either Flow Controller is
frequently used in conjunction with the S-3A Oxygen analyzer and CD-3A
Carbon Dioxide analyzer. The Model R-1 includes a flow meter, pump, and a
needle valve in a single cabinet. Model R-2 (shown above) includes 2 flow
meters, pump, and 2 needle valves.

S-3A/I and S-3A/II
Oxygen Analyzers
Introduction
The Applied Electrochemistry Model S-3A
Oxygen Analyzer continuously measures the
concentration of oxygen. There are two
models: The S-3A/I Single-Channel Analyzer
and the S-3A/II Dual-Channel Analyzer. Both
instruments feature the same high accuracy,
rapid response, and fine sensitivity.
Features:
•
•
•
•
•
High
accuracy
at
all
oxygen
concentrations
Rapid response-ideal for accurate
breath-by-breath measurements
High sensitivity plus exceptional
stability—capable
of
detecting
changes of 0.001% oxygen at air
composition
Solid ceramic oxide sensing element
for
long
term
maintenance-free
operation
Single gas calibration (room air may
be used)
The Gold Standard in laboratory
oxygen analysis for over 30 years,
worldwide.
S-3A/I Single-Channel
Capabilities
A complete Model S-3A consists of a sensor,
readout/control unit, and cable. When the
sample gas is passed through the sensor, a
voltage that is a function of the oxygen
concentration of the gas is generated. This
voltage is fed to the readout/control unit via
a connecting cable.
The optional R-1 (Single Channel) or R-2
(Dual Channel) Flow Control Unit can be used
to draw the sample through the sensor. Each
flow control unit contains a pump, a needle
valve, and a flowmeter for each channel.
Other gas handling equipment can be used if
preferred.
