Carbon monoxide gas sensor - オーティウェル | ガスアナライザーメーカー

Description

Electrochemical Carbon monoxide gas sensor utilizes the electro-chemical activity of the gas under measurement to undergo elec-trochemical oxidation or reaction inside it, thereby converting the content of the gas under measurement into a current (or voltage) signal output to distinguish the composition and concentration of the gas.

Functions Features

Fast response and recovery time
High stability
Robust at humidity and temperature extremes
Meets sensor requirements outined in: AQ6205-2006 and EN5544
