Otywell | Gas Analyzer Manufacturer
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
