 CIRAS-DC CO2 and h2O Gas Analyzer

 

  • The CIRAS-DC is a dual channel, true differential infrared gas analyzer featuring 4 independent gas analyzers (2 for CO2 and 2 for h2O).  The CIRAS-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.  As such it is capable of resolving small differences between two gas streams in real time.

  • CIRAS-DC gas analyzer features a high technical specification and quality workmanship ensuring accuracy, precision and reliability. 

  • Designed to be controlled and operated through a standard PC, with integral logging for stand-alone operation.

  • 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.

  •  High precision, non-dispersive infrared gas analyzers for CO2 and H2O
  •  The CIRAS DC is a true differential system. It features 4 independent, non-dispersive gas analyzers for accurate, simultaneous measurement of both CO2 and H2O eliminating the problems associated with "gas switching" systems. 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.
  • CO2 Range : 0-2,000 ppm (up to 9,999 ppm)
•     Fast response
•     Analog & digital (RS232) linear output
•     Excellent stability achieved by built-in auto-zero facility. It automatically corrects for sample cell   contamination, dirty optics and drift in electronics.
  • Unique, Built-In Self-Calibration System- allowing for simple, accurate calibration of the CO2 analyzers. This is very useful for researchers studying from remote sites. An H2O calibrator is supplied with each system as standard.
•     Fully compensated for changes in temperature, pressure and gas interactions.
•     Built-in sampling pump with mass flow controllers
•     Insensitive to vibration, no moving parts ensuring high reliability
•     Internal & external logging
