Honeywell’s 4909 series comprise ball valve assemblies that can be mounted in large pipe diameters or directly in the side of a process tank to measure conductivity in applications ranging from sensitive ultra-pure water applications to highly conductive industrial processes.
While the 4909 series comprises ball valve, mounting nipple, stuffing box assembly and the conductivity cell, the 4908 is the just the replacement cell used with the 4909 assembly. The ball valve assemblies are available in both stainless steel and CPVC plastic.
Honeywell offers an array of cell constants allowing users to select the one best suited for their application. Equipped with a wide range of capabilities, these cells ensure accurate conductivity measurement.
