1.1 Overview
These cells form the sensing network for industrial analyzers and transmitters designed to make continuous
measurements of electrolytic conductivity. The cells are primarily suited to measurements in effluents of
ion-exchangers and distillation columns; but appropriate constants are provided for many other
applications, including measurements in micro-electronic component washing and plating-rinse effluents.
Universal in mounting, any of the cells can be arranged for immersion (for applications where the
temperature does not exceed 85°C), insertion (1” NPT) or flow type sampling. The latter can be achieved
by use of a CPVC flow housing, a 1” pipe tee (schedule 40), or 1-1/4” plastic tee (schedule 80) installed in
a process line or bypass line as pictured in

ATTENTION
Please note that specific parameters of your process may prohibit the use of nickel elements. For example,
use a platinum-element cell if the cell will measure or be exposed to regeneration acids or bases.

Introduction
The cell constant is selected according to the range of the measuring instrument used and the solution
measured. In general, a high-constant cell is used for solutions having low electrical resistance (high
conductivity) and a low-constant cell is used for solutions having high electrical resistance (low
conductivity). Automatic Temperature Compensation (ATC) during the measurement is provided by a
built-in temperature sensing network located near the cross-channel or guard-tube holes.
The cells are molded from Polyethersulfone (PES) which is resistant to most corrosive chemicals over a
wide range of temperatures. (A common exception is chlorinated hydrocarbons.) Sample solutions come
into contact only with the above plastic and the platinum or nickel electrode surface. Any cell can be
supplied with either electrode material.
