Kohlenstoffmonoxid (fachsprachlich Kohlenstoffmonooxid, gebräuchlich Kohlenmonoxid) ist eine chemische Verbindung aus Kohlenstoff und Sauerstoff mit der Summenformel CO. Kohlenstoffmonoxid ist ein farb-, geruch- und geschmackloses sowie toxisches Gas. Es entsteht unter anderem bei der unvollständigen Verbrennung von kohlenstoffhaltigen Stoffen bei unzureichender Sauerstoffzufuhr.

· 250+ Gas Detection System Interview Questions and Answers, Question1: What is a ‘combustible gas mixture’? Question2: Explain the operating principle of a gas detection system. Question3: Why is gas detection as important as fire detection? Question4: What are the components used in a gas detection loop? Question5: What is a ‘flame arrester’ in a gas sensor?
Frequently Asked Questions. Q: What is the difference between infrared and electrochemical gas sensors? A: The main difference is in the measurement method. In electrochemical sensors, the sensitive element remains in direct contact with the gas and a chemical reaction occurs. This causes the sensor element to be contaminated by the reaction products which leads to loss of sensitivity ...
NO2 gas sensor (cell) life expectancy is 2 years, normal operation environment. If gas sensor (cell) is intensively exposed for fumes (gas) the life time is shorter. If gas sensor (cell) is less exposed for fumes (gas) the life time can be longer. Questions & Answers on Gases in F&G What kind of substance is carbon monoxide?
CO sensors can become saturated with target gas CO. If enough CO enters the sensor beyond maximum range (that listed in the instruction manual), the sensor is unlikely to be able to process all applied gas. When this scenario occurs, the electrolyte becomes saturated. A saturated sensor will continue to show high gas readings until the gas can be processed from the electrolyte. If saturation ...
Gas Sensors. With more than 300 products detecting 28 different gases, we offer the widest range of gas sensors in the market today. Our sensors are available in variety of formats to satisfy the precise requirements of specific applications. City Technology provides critical gas sensing solutions wherever safety is paramount.
The oxidation potential of CO gas (as expressed in Equation 1) is lower than the oxidation potential of the electrode（2H+ + 2e-⇔ H 2), oxidation of CO has less noble potential than deoxidization. Since this reaction occurs easily, no external energy is needed to stimulate the sensor’s chemical reaction, unlike with three-electrode type sensors. As a result, this two-electrode type ...

Carbon monoxide (CO) is a colourless, odourless, tasteless, poisonous gas produced by incomplete burning of carbon-based fuels, including gas, oil, wood and coal. Carbon-based fuels are safe to use. It is only when the fuel does not burn properly that excess CO is produced, which is poisonous. When CO enters the body, it prevents the blood from bringing oxygen to cells, tissues, and organs.
Dieses toxische Gas kommt vor allem in Abgasen von Benzinmotoren vor. Der Sensor wird zur Steuerung von Lüftungen und zur Alarmierung für den Personenschutz eingesetzt. Die mikroprozessorgesteuerte Elektronik des Sensors, angepasst an die spezifischen Eigenschaften der Messzelle, erlaubt eine schnelle und zuverlässige Signalauswertung. Die gemessene …
Electrochemical sensors are devices that measure flue gas constituents (O2, CO, NO, NO2, SO2, H2S) through the principle of ion selective potentiometry The sensor contain a electrolytic matrix that is designed for a specific gas to be detected. Two or three electrodes (again gas specific) are placed in this matrix and an electrical field is applied. Flue gas enters the sensor and chemically ...
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 time-weighted average.

· That sensor is also sensitive to temperature and humidity fluctuations. If you want high selectivity for particular compounds, you will want to investigate other gas sensing technologies such as gas pellistor, electrochemical (EC), PID, etc. EC sensors in particular can give you good specificity for certain target analytes like CO, NO2, SO2, etc.
The Gas Tracer has a version where the charcoal filter is removed from the CO sensor to allow for detection of H2S. The readout is displayed as ppm CO (not H2S), and there is no way to differentiate CO from H2S readings. GX-2012: Has the capability of H2S detection with a dedicated H2S sensor. With the Gas Tracer, H2S sensor …
