How Do Electrochemical Sensors Work? - Analytical ...

· 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.

Electrochemical Sensor - Systech Illinois

Historically, the use of electrochemical sensors had its beginnings in the 1950s, through the monitoring of industrial oxygen [4]. Labor laws related to the health and safety of the workers required the monitoring of toxic gases and fuels in confined spaces, prompting a burst of research into electrochemical sensors that could exhibit good selectivity for the detection of different gases. Leland C. Clark proposed the oxygen sensor …

Oxygen sensor - Wikipedia

An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analysed.. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Dr. Günter Bauman. The original sensing element is made with a thimble-shaped zirconia ...
