SKU: 396P
pH/ORP sensor designed for harsh, dirty, abrasive applications — lime slurry waste treatment, paper-machine headbox, pigment/dye production, and any process with large quantities of suspended solids. Wear-resistant body and reference geometry that survives where standard 3900 sensors fail in months. Insertion mounting standard. VP connector option (396PVP). The Rosemount choice for the dirtiest pH measurement jobs.

Premium pH/ORP sensor for high-temperature, high-pressure, fouling/coating applications — robust design significantly prolongs sensor life in complex chemistries (chlor-alkali, semiconductor, hydrocarbon). Resists fouling, coating, and reference-junction poisoning that defeat standard pH sensors. VP variable-pin connector option (3300HTVP) for VP-cable compatibility with the 1056 / 1057 / 5081 transmitters. The Rosemount Analytical workhorse for severe-service pH measurement.

Mid-tier general-purpose pH/ORP sensor with double-junction reference — protects the reference element from poisoning ions (ammonia, chlorine, cyanides, sulfides) that kill single-junction reference sensors. Wide range of installation styles: insertion, submersion, retractable. Cost-effective workhorse for water/wastewater, general process, and any application where the 3300HT premium would be over-spec. VP version (3900VP) for variable-pin connector compatibility.
