1 Overview
1.1 Structure and function
The ConOx is a modular sensor for conductivity, dissolved oxygen (DO) and
temperature. It consists of two basic components:
l Conductivity basic module, according to the quadripole measuring princi-
ple, with integrated temperature sensor
l Removable dissolved oxygen module, according to the galvanic measur-
ing principle
