pH in Refining & Petrochemical

Petrochemical and refinery operations are harsh environments which therefore require robust sensor designs. Specialized mechanical insertion assemblies are required to avoid downtime and alleviate safety concerns when maintaining or replacing pH sensors. The appropriate housing material (Hastelloy, PEEK, Kynar, etc.) is selected based upon the sample matrix and temperature requirements. The reference junction is equally as critical. The Tuff-Tip is a unique design that provides a low profile guard for the pH glass without protruding prongs that accumulate process material or debris. It incorporates a large ceramic or Teflon junction that reduces the chance of process material fouling the porous junction. The Tuff-Tip also aids in keeping the pH membrane and reference junction clear from coating.
