Sensor Selection for GDS68SXP Natural Gas Odorant Monitors Electrochemical Sensors for Natural Gas Odorants Natural gas odorants are typically composed of blends of mercaptans, tetrahydrothiophene, dimethyl sulfide and other specialized compounds. They must be chemically stable and not react or cause damage to gas components or pipes.
An electrochemical sensor is an electrochemical cell that employs a two or threeelectrode arrangement and in which concentration measurements can be performed at steadys tate or transient. Depending on the mode of operation, electrochemical sensors are divided into potentiometric, amperometric, and electrocatalytic sensors.
An electrochemical gas sensor is available for just about any target gas, and across a wide range of sensitivities, such as a highly accurate electrochemical CO sensor. Although they are designed to be as specific as possible, most electrochemical sensors will respond in some manner to gases other than the target gas.
· Electrochemical sensors are used for detecting oxygen and toxic gases. More specifically, they measure the concentration of a specific gas within an external circuit. This is done by method of oxidation or reduction reactions. These reactions generate the positive or negative current flow through said external circuit.

· Hi, people! I''ve been looking for a way to measure the specific gas, ethylene which is forcing the ripening of fruits. So, I''ve looked up to the possibility of gas sensors, as follows: Sensor Name Gas to measure MQ2 Methane, Butane, LPG, Smoke MQ3 Alcohol, Ethanol, Smoke MQ4 Methane, CNG Gas MQ5 Natural gas, LPG MQ6 LPG, butane MQ7 …
· Most electrochemical gas sensors are used in diffusion mode, in which the gas sample in the surrounding environment enters the sensor through a small hole in the front of the sensor (through the natural flow of gas molecules). Some devices use an air pump to pump air / gas samples into the sensor. A polytetrafluoroethylene film is installed at ...

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.
Oxygen Gas Analyzer Models. Our O2 sensor is of the longlife electrochemical “fuel cell” type. This sensor produces a small millivoltage output that is directly proportional to the oxygen detected. This output is then amplified and displayed on a digital readout meter and is also available as an output to your site data recorder.
