EC9820 - CO2 Analyzer

The EC9820 CO2 analyzer combines microprocessor control with NDIR gas filter correlation photometry to provide accurate measurements of CO2 with minimal interference from CO and/or H2O in the range of 0-3000 ppm, resolution equals 0.1ppm or to a range of 0-full scale from 0-200ppm to 0-3000ppm with 0%, 5%, 10% offset.

• Internal data logger users Flash Rom. Up to 175 of 5 minute averaged data can be remotely downloaded for further analysis, report generation or archiving.
• Software controls all instrument functions including the performance of diagnostics, system status, output signal linearity and the calculation of CO2 concentration
• Battery or solar power operation is possible using the optional 12 VDC power supply
• Data accessed via RS232, USB interface or optional ethernet connector

The EC9820 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 temperature/pressure changes and can be displayed in units of ppm or mg/m3. The EC9820 allows for a manual, timed or remote initiated zero/span calibrations.

Features

• Accurate and specific measurements of CO2 with minimal interference from CO or H2O using proven gas filter wheel correlation technology.
• The EC9820 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.
• Optional permeation dryer for removal of H2O from sample air
• 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 power 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.
