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 …

Common Testing Questions - Testo, Inc

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 ...

Frequently Asked Questions - Gas Sensor Technology

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 ...

Kohlenstoffmonoxid – Wikipedia

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.

Carbon monoxide (CO) optical gas sensor based on ZnO thin ...

· Optical gas sensors provide an alternative over the conventional conductometric gas sensors. Carbon monoxide (CO) gas is generally regarded as one of the most dangerous air pollutants, hence, a room temperature operated CO gas sensor using ZnO sensing film deposited on Au coated prisms has been developed using an indigenously developed surface plasmon resonance (SPR) …

Carbon monoxide awareness - Gas safety - HSE

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.

Operating principle ‐Electrochemical-type gas sensor

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 ...
