The EC9820 Model of Analyzer of Carbon Dioxide (CO2), manufactured by Ecotech, is mainly used for emissions monitoring for ambient and stack utilization. This device integrates microprocessor control with NDIR gas filter correlation photometry. It provides precised measurements of CO2 with low interference from CO and/or H2O in the range of 0-3000 ppm, resolution equals 0.1 ppm or to a range of 0 to full scale from 0 to 200 ppm from 0 to 3000 ppm with 0%, 5%, 10% offset.
Moreover, it has software which controls all facility functions including the performance of diagnostics, system status, output signal linearity and the measurement of CO2 concentration. It can also generated with battery or solar power generation which is possible with the use of optional 12 V DC power supply, and built with data accessed via RS232.
