Understanding a Gas Sensor | Jaycon Systems

· Gas sensors serve to measure the concentration of gases in the environment. There are many different types depending on what you want to measure. In this case, the MQ4 gas sensor can measure Liquefied Petroleum Gas (LPG), Methane (CH4), Hydrogen (H2), Carbon Monoxide (CO), alcohol, and smoke concentrations. The sensor has a built in variable resistor that changes its value …

Frequently Asked Questions | CDC

An odor from your gas refrigerator can mean it could be leaking CO. When you buy gas equipment, buy only equipment carrying the seal of a national testing agency, such as Underwriters’ Laboratories. Make sure your gas appliances are vented properly. Horizontal vent pipes for appliances, such as a water heater, should go up slightly as they go toward outdoors, as shown below. This prevents CO ...

Gas Leakage an overview | ScienceDirect Topics

Instances of gas leakage from naturally occurring CO 2 reservoirs serve as analogues for potential releases from geologic storage sites (Lewicki et al., 2007). A review of these sites indicate CO 2 can accumulate and be released from storage sites located at a wide range of depths, and that many natural CO 2 releases can be correlated with specific triggering events, such as magmatic or ...

CO and CO2 – What’s the difference? |

The molecular weight of CO is , where the molecular weight of CO2 is This means that the CO2 gas is much more dense than CO. CO2 will collect near floor level while CO will collect closer to the ceiling. OSHA lists danger levels for CO beginning at 35 ppm, and for CO2 starting at a 5,000 ppm timeweighted average.
