CO2
& H2O Gas Analyzers
For over 25 years, PP Systems has been
manufacturing high quality CO2 & H2O infrared gas
analyzers for researchers and customers from a wide
variety of disciplines throughout the world. We
are considered a leader in CO2
and H2O
infrared gas analysis measurement instrumentation and
our
analyzers are in use in over 100 countries worldwide.
Our innovative
Auto-Zero
Measurement Principle ensures the greatest accuracy,
reliability and long term stability that many of our
customers have come to expect throughout the years.
Our CIRAS-2 SC and CIRAS-2 DC
laboratory gas analyzers feature a high
technical specification and quality workmanship ensuring
accuracy, precision and reliability. They are both
designed to
be operated through a standard PC
for stand-alone operation. Having said that, an
optional 12V lead acid battery can be supplied for both
instruments for portable applications if required.

CO2 & H2O Gas Analyzers: For users that
demand accuracy and stability for high level research
|
|
The CIRAS-2 SC is a single channel
infrared gas analyzer for accurate, absolute measurement
of CO2 and H2O
in µmol mol-1 of a single gas stream.
 |
The CIRAS-2 SC is a single channel
infrared gas analyzer for accurate, absolute measurement
of CO2 and H2O
in µmol mol-1 of a single gas stream. It features
2
independent, non-dispersive gas analyzers for accurate,
simultaneous measurement of both CO2
and H2O. There are no moving parts. The analyzers
(reference and analysis) include an infrared source,
gold plated and highly polished sample cells and
detectors. The analyzers act as absorptiometers
measuring only in the 4.26 µm (CO2)
and 2.60 µm (H2O)
wavebands ensuring accurate, rapid and stable results. The analyzers are thermostatted and completely insulated
to ensure accurate measurements under changing ambient
temperatures. This eliminates problems associated
with software corrections.
Our history and expertise in CO2
& H2O infrared Gas analysis
design speaks for itself. The design of the CIRAS
ensures an inherent calibration stability. This has been
confirmed by over 25 years experience of the technology.
The CIRAS system does not require calibration. To
ensure proper operation and calibration of the
analyzers, we do recommend periodic checks to confirm
system integrity.
Measurement
Ranges
CO2:
0-2000 µmol mol-1
(Optimal)
0-10000 µmol mol-1
(Maximum)
H2O:
0-Dewpoint
For measurements at elevated CO2
concentrations, the CIRAS-2 SC is factory calibrated up to
10000 µmol mol-1 as standard.

CIRAS-2 DC
The CIRAS-2 DC is a dual channel infrared
gas analyzer for accurate, differential measurement
of CO2 and H2O
in µmol mol-1 from 2 gas streams (reference
and analysis).
|
The CIRAS-2 DC is a dual channel, true differential
infrared gas analyzer featuring 4 independent gas analyzers (2 for CO2
and 2 for H2O).
The CIRAS-2 DC is capable of accurate, absolute
measurement of CO2
and H2O in
µmol mol-1 of two gas streams and displays
the results as the absolute concentration of one gas
stream (the reference) and the difference between the
two gas streams. The analyzers (reference and
analysis) include an infrared source, gold plated and
highly polished sample cells and detectors. The
analyzers act as absorptiometers
measuring only in the 4.26 µm (CO2)
and 2.60 µm (H2O)
wavebands ensuring accurate, rapid and stable results. As such it is capable
of resolving small differences between two gas streams
in real time. The analyzers are thermostatted and completely insulated
to ensure accurate measurements under changing ambient
temperatures. This eliminates problems associated
with software corrections.
Our history and expertise in CO2
& H2O infrared Gas analysis
design speaks for itself. The design of the CIRAS
ensures an inherent calibration stability. This has been
confirmed by over 25 years experience of the technology.
The CIRAS system does not require calibration. To
ensure proper operation and calibration of the
analyzers, we do recommend periodic checks to confirm
system integrity.
This type of instrument (true differential analyzer)
is the preferred option for plant photosynthesis and
respiration measurements where differential
concentrations need to be resolved to a high degree of
accuracy and precision.
