NE4-NO Electrochemical Nitric Oxide Gas Sensors Are Suitable For Many Applications

Features:

1. General

Nemoto NE series sensors were developed for industrial applications, and NE4-NO is a newly developed electrochemical nitrogen monoxide gas sensor. Shape and pin positions are compatible with others, but the stability, repeatability, durability and reliability are superior to others

. Features and applications are as follows.



2. Detection principle

Electrochemical sensor consists of working electrode on which oxidization or reduction takes place, counter electrode on which reduction or oxidization takes place, and reference electrode which can monitor and keep the voltage at constant. Structure of electrochemical sensor is shown in the following figure, nitrogen monoxide gas diffuses through membrane into working electrode, and it is oxidized to nitrogen dioxide at working electrode in case that the designated bias voltage is supplied. Consequently generated proton at working electrode reacts with hydroxide ion, and then, water is generated at this reaction. Water molecule proceeds to working electrode, and increase at counter electrode by generated current of this serial reaction. Total reaction is in the below described. NO gas concentration is proportional to the current that is generated by this serial reaction
