PH & ORP Sensors

PREI Instrumentation supplies pH and ORP measurement sensors that help facilities monitor water quality accurately and maintain effective control over industrial processes. Our range includes inline pH sensors, precision pH/ORP systems, and pure water sensors, providing options for demanding industrial environments and high-purity water applications.

While pH measures how acidic or alkaline water is, oxidation-reduction potential (ORP) indicates its oxidising or reducing tendency, providing useful information for process monitoring and assessing treatment conditions. Our pH and ORP measurement sensors support these complementary measurements, helping your team track changes and make informed operational decisions. For challenging applications, we offer sensor options designed to withstand aggressive media, solvents, volatile organic compounds (VOCs), dehydration, and high temperatures.

These products form part of our comprehensive water analytics offering, alongside ammonium and chlorine ISEs, conductivity sensors, and other analytical instrumentation.
