1 Overview
1.1 Structure and function
The LFOx1400(-ID) is a modular sensor for conductivity, dissolved oxygen
(DO) and temperature. It consists of two basic components:
 Conductivity basic module, according to the quadripole measuring princi-
ple, with integrated temperature sensor
 Removable dissolved oxygen module, according to the galvanic measur-
ing principle
