Technical Specifications
Powerful Software
Simple, intuitive and menu-driven software is designed into
the system for system setup, operation, recording and data
management. On-line help is available throughout the
software to guide you every step of the way.
Convenient, pluggable terminal block for analog signals.
Analysis Method
Non-dispersive infrared, configured as an absolute
absorptiometer with micro-processor control of
linearization. Two independent gas analyzers
simultaneously measure absolute CO2 and H2O from
a single gas stream. All measurements corrected for
temperature and pressure.
CO2 Measurement Range
0-10000 µmol mol-1
CO2 Precision
H2O Measurement Range
0-75 mb
H2O Precision
Bandwidth (CO2 and H2O)
10 Hz (sampling rate). Sample data is averaged and
output every 1.6 seconds.
Pressure Range
65-115 kPa
Air Sampling
User adjustable from 50-100 cc min-1 using integral DC
pump with mass flow controller.
Auxiliary Port
For connection to external sensors.
Terminal Block
Two 8 pin terminal blocks for simple connection to
external devices.
Digital Output
Analog Output Channels
4 Analog output channels available. Users can
configure system to output CO2 reference, CO2
analysis, CO2 differential, H2O reference, H2O analysis
and H2O differential.
Analog Output Range
0-2.5V or 0-5V
Analog Input Channels
2 Analog input channels available for use with
external sensors
Analog Input Ranges
0-1V or 0-5V
Data Storage
512 MB flash memory for programming and data
storage. Unlimited data storage using USB thumb
drives (memory sticks).
Microprocessor Speed
