Abstract

An electrochemical sensor device providing long term signal stability through a structure and relation of components effective to provide substantially uniform current flux at all points across a working electrode and a counter electrode of a three electrode system within an electrolyte container having a hydrophobic membrane permeable to a selected component to be measured and accessible to a fluid to be monitored.
