pH and Conductivity

pH measurements in the D and E stages have historically been among the most difficult applications in the pulp mill. The high pulp consistency of the process stream and harsh bleaching chemicals degrade the performance of most general purpose sensors. Those sensors tend to require cleaning regularly and frequently, and they may not be able to withstand the strongly oxidizing environment.

The TUpH Model 398R pH and ORP sensors are well-suited for this kind of application. The wide-area junction provides resistance to coating, while the patented helical pathway prevents process intrusion into the inner reference chamber. Construction materials of Tefzel and Kalrez are used to withstand the strongly oxidizing environment.

Spartan’s results-proven applications and solutions can help you accurately predict performance, efficiently manage your assets and logistics, minimize safety risks, increase your productivity, and, most importantly, maximize profit.
