Honeywell offers a wide variety of conductivity cells to satisfy your process needs, from sensitive ultra-pure water applications to highly conductive industrial processes. Honeywell cells are constructed of rugged materials, guaranteeing longer cell life. An extensive range of cell constants from 0.01 to 50 (depending on the model) allows you to select the conductivity cell best suited for your application, providing a wide range of capabilities and ensuring accurate conductivity measurements. All conductivity cells have integral temperature compensators that are compatible with Honeywell instrumentation. An assortment of mounting options—immersion or flow-thru—reduces your installation costs. Honeywell’s complete line of conductivity instrumentation— cells, analyzers/controllers and transmitters—ensures the most reliable conductivity measurements available.

The 4909 Series cells include a ball valve in which the cell is mounted. This allows for the cell to be removed form the process without having to shut down the process and drain the pipe or tank. The ball valve assembly can be made of stainless steel or CPVC. The 4908 Series is the replacement cell only that is used with the ball valve assembly. Cells can be supplied with either nickel, Monel or platinum electrodes, and will provide continuous, reliable measurements at temperatures up to 140 degrees C and pressures up to 150 psig. Pressures must be reduced to 50 psi before attempting to install or remove a cell from the ball valve.
