Carbon monoxide concentration determinations of 99.4 and 95.4 ppm (95.6% and 91.7% recovery respectively) were obtained. Previous work had demonstrated that the results for this procedure tend to be slightly lower than expected ( 5.24 ).

This bond is a bit unusual due to the oxygen atom contributing more electrons than the carbon atom (oxygen shares 4 electrons while carbon shares only 2 electrons), called coordinate covalent bonding. The results will be in parts per million (ppm) of carbon monoxide in your breath. Reading Suggests; 10 ppm and over: recent exposure to a high level of carbon monoxide.

The GS-CM4-W Series carbon monoxide detector uses an electrochemical sensor to monitor the carbon monoxide level and outputs a field-selectable 4-20 mA , 0-5 or 0-10 Vdc. The sensing range and output may be scaled to either 100, 150, 300, 400 or 500 ppm via the on-board menu. A front panel LCD is standard to ensure easy setup and operation.

Carbon monoxide is called “the silent killer” for good reason. You could be standing in a room full of it and not know it. In high concentrations (around 2,000 ppm) you’ll become unconscious in a few minutes.

Airgas Part #:X03HE74Z3001872. SDS The HOBO Carbon Monoxide Data Logger monitors carbon monoxide (CO) levels in areas such as garages, terminals, loading docks, construction sites, furnace rooms, office buildings and living areas. Convenient battery operation eliminates the need to run wires for AC power, making it easy to deploy the HOBO CO data logger at various potential hot spots. 4-CO-500 CARBON MONOXIDE SENSOR 0-500 PPM CO EURO-GAS MANAGEMENT SERVICES LTD, CHURSTON HOUSE, BASCOMBE ROAD, CHURSTON FERRERS, DEVON, TQ5 0JJ, UK : +44 (0)1803 844414 Fax: +44 (0)1803 844224 sales@euro-gasman.com www.euro-gasman.com SPECIFICATION –4 SERIES Operating Principle: Electrochemical, 3-electrode cell Carbon Monoxide production: In a normal and perfect combustion process, molecules of fuel and air are combining to create Carbon Dioxide (CO2) and Water Vapor (H2O). In most fuel burning appliances, the combustion process is not quite perfect, and instead of oxygen and carbon combining perfectly, a single carbon atom will combine with one oxygen atom and CO will be the result. 4=severe Carbon Monoxide can affect you when inhaled.
