As the wheel turns round, the light beam passes alternati-vely through the CO cell and the empty cell and then through an interference opticalfilter before reaching the optical detector. If the sample contains CO, the referencebeam will not be attenuated by it because it was already attenuated by the CO of thereference cell. The measure beam however will be attenuated by the CO in thesample. The analyzer was developed to meet customers’ require-ment for reduced and easier maintenance. Equipped withsealed gas cells located in the airtight thermo-regulatedmeasurement module, the CO12M combines a powerful,easy-to-use interface with state-of-the-art componentsand design technology. Real-time calibration graphs can be displayed during spancheck operation. Multi-tasking software allowing advan-ced calculation such as wind direction averaging, combi-ned with the LCD graphic display, gives a user-friendlyaccess to the instrument set-up, as well as the status andmaintenance parameters. Real-time synoptic, auto-dia-gnostic and maintenance data screens can be displayedwhile the instrument is operating. The new electronicsallow enhanced data storage of more than two months of15 minute averages, and total remote troubleshooting dia-gnostic capabilities via modem, using the analyzer com-plete display and functions emulation.Equipped with the optional ESTEL I/O analog & digital board, the CO12M can be easi-ly interfaced with other equipment and can be operated as a stand alone unit able tostore several months of data.Specifications subject to change without prior notice ref. : 04/03 Analyseur CO12M Angl.2CO• Ranges : 0-10/ 25 / 50 /100 / 200 ppm or user selectable ranges • Autoranging between two-user specified ranges• Noise (s) : 25 ppb• Lower detectable limit (2s): 50 ppb• Response time : automatic and program mable (minimum 30 sec)• Zero drift : less than 0.1 ppm / 24 hless than 0.1 ppm / 7 days• Span drift : less than 1% / 24 hless than 1% / 7 days• Interference rejection ratio :- H2O : less than 1/200 000 - CO2 : less than 1/70 000 • Linearity : +_ 1 % of F.S.• Pressure and temperature compensation• Internal sample pump• Sample flow rate : 1 lpm• Averaging time : programmable from 1min. to 24h• Data storage : more than 2 months 1/4 h average values• Chassis : 19" rack mountable, 3U• Dimensions : 545 mm x 483 mm x 133 mm (L x W x H)• Weight : 8 kg (17 lbs)• Power : 115 V, 60 Hz - 230 V, 50 Hz• Power consumption : 50 VA• Operating temperature : 5 – 40 °C (typical as per US EPA 10 - 35° C)• Digital output : 2 RS 232 or RS 422 ports• PVDF sample filter holder• Valves block for selection of customer – supplied zero and span gasOptions :• ESTEL electronic board (1 or 2) with :- 4 independent analog inputs- 4 independent analog outputs- 4 remote control inputs- 6 dry contacts• Memory extension (1 year of 1/4 h average values)• 24 V DC power supply for on-board applications• CO2 measurement in ambient air • CO/CO2 measurement in ambient air• Wall mounted weather proof enclosureDistributed by : IR Gas Filter Correlation Carbon Monoxide Analyzer - model CO12MSpecifications : Main Features:ISO 9001111, boulevard Robespierre - BP 4513 - 78304 POISSY Cedex - FRANCETel. : +33 (0)1 39 22 38 00 - Fax : +33 (0)1 39 65 38 08Web : www.environnement-sa.com - e-mail : info@environnement-sa.comISO 14001ECOPASSCO12M Angl.
