EC9820T CARBON DIOXIDE ANALYSER The EC9820T Trace Carbon Dioxide Analyser combines microprocessor control with NDIR gas filter correlation photometry detection to measure CO2 with minimal interference from CO and H2O. The CO2 concentration is automatically corrected for gas temperture/pressure changes and can be displayed in units of ppm or mg/m3. The EC9820T allows for a manual, timed or remote initiated zero/ span calibration. • Accurate and specific measurements of CO2 with minimal interference from CO or H2O using proven gas filter wheel correlation technology. • The EC9820T uses a long life infrared (IR) source and advanced materials in the gas filter wheel to deliver trouble free operation and minimum maintenance. • Variable sample flow rate allows for faster purging during zero and span cycles. The variable flow rate enables the analyser to obtain more data points at ‘steady state’ zero and span conditions. • On-board software controls all internal adjustments including diagnostics, instrument status, zero and span calibrations and calculation of CO2 concentration. • Internal data logger uses flash ROM. Up to 175 days of 5 minute averaged data can be remotely downloaded for further analysis, report generation or archiving. • Battery or solar powered operation is possible using the optional 12 VDC power supply. • Stored data can be retrieved via RS232, USB interface or the optional Ethernet connection and uploaded to a TCP/IP network. • Ethernet option facilitates data download from an analyser connected to the internet via a standard web interface. This feature also supports remote access to instrument parameters and the status screen.
