  • Page 4: Introduction

    1 INTRODUCTION This conductivity analyzer has been designed for continuous monitoring and control of conductivity. It is available in wall-/ pipe-mount or panel-mount versions and can be used with either one or two sensors, each with a temperature input channel. When used with two sensors, readings can be compared to produce a range of extrapolated values.
