The EC9820 Carbon Dioxide Analyser , developed and manufactured by Ecotech in Australia, combines microprocessor control with NDIR gas filter correlation photometry detection to measure CO2 with minimal interference from CO and H2OThe CO2 concentration is automatically corrected for gas temperaturepressure changes and can be displayed in units of ppm or mgm3. The EC9820 allows for a manual, timed or remote initiated zerospan calibrations.Special features:The EC9820 uses a long life infrared (IR) source and advanced materials in the gas filter wheel to deliver trouble free operation and minimum maintenanceVariable 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 conditionsOptional permeation dryer for removal of H2O from sample airInternal data logger and communication via RS 232, USB, TCPIPEthernet 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
