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.
