Top five reasons why monitoring the CO2 concentration is a ...

02/02/2017· Carbon dioxide concentrations of more than 20,000 ppm can cause panting. Concentrations above 100,000 ppm of CO2 will cause loss of consciousness and tremors. Values greater than 250,000 ppm have the potential to lead to death. Carbon dioxide could be hazardous in 1 of 2 ways: by displacing oxygen in the bloodstream or when acting as a toxin.


CO2 Carbon Dioxide Gas Exposure limits InspectAPedia

Collectively, these studies suggest that carbon dioxide concentrations above 1800 mg/m3 (1000 ppm) are indicative that there is an inadequate supply of fresh air, although complaints have been documented at concentrations as low as 1100 mg/m3 (600 ppm). However, from a review of the direct physiological effects of exposure to carbon dioxide, as opposed to subjective symptoms, a higher maximum ...


Go Direct® CO2 Gas Sensor User Manual – Vernier

Go Direct CO 2 Gas measures gaseous carbon dioxide levels in the range of 0 to 100,000 ppm by monitoring the amount of infrared radiation absorbed by carbon dioxide molecules. Carbon dioxide gas moves in and out of the sensor tube by diffusion through the vent holes in the sensor tube. The sensor uses a small light to generate infrared radiation (IR). The IR source is located at one end of the ...


How reliable are CO2 measurements? Skeptical Science

Consequently, the trend in Mauna Loa CO2 ( ppm per year) is statistically indistinguishable from the trend in global CO2 levels ( ppm per year). If global CO2 was used in Figure 1 above, the result "hockey stick" shape would be identical. Figure 2: Global atmospheric CO2 versus Mauna Loa CO2 . The following video is a graphic example of where our data for CO2 levels comes from. It ...

Converting CO2 ppm to mmHg — Parallax Forums

14/05/2013· Wouldn''t it be: mmHg(CO2) = mmHg(system) * (reading from sensor in ppm) / 1,000,000 I''m trying to remember my gas laws (which I used to teach). I think each molecule of gas contributes equally to the overall pressure (within reason) so there''s a 1:1 relationship between PPM and pressure.

Parts Per Million (ppm) Converter Lenntech

Parts per Million by Weight in Water The concentration in ppm of gas in water is meanly meant by weight. To express this concentration with metric units the density of water is needed. The density of pure water has to be by definition kg/m 3 at a temperature of °C and standard atmospheric pressure, till 1969. Till then this was mean definition for the kilogram. Today''s the kilo ...

How to calculate the CO2 emission from the fuel ... Ecoscore

You will see that the CO2 emissions per kg of Hgas is higher than that of Lgas. Hgas, however, contains more energy, so you will need less kg of gas per 100 km, which ensures that, at least in theory, the average CO2 emissions from CNG vehicles is independent of the gas type used. Lowcalorific: 1 kg of Lgas consists for 61,4% of carbon, or 614 grammes of carbon per kg of Lgas. In order ...

Carbon dioxide can be lethal. CO2 concentrations of more than 20,000 ppm can cause coughing. Levels above 100,000 ppm cause unconsciousness and tremors. Concentrations of more than 250,000 ppm become a lethal hazard as the high concentrations either behave like poison in the body or displace oxygen from the bloodstream.
