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 Figure 1-1.

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.
