High Temperature PH&ORP Sensor Manufacturers & Factories in the San Francisco Market

Elevated temperatures accelerate two primary failure mechanisms: the dissolution of the pH-sensitive hydrated glass gel layer and reference electrolyte boil-off or expansion. In standard sensors, standard 3M KCl electrolyte expands, blows past the porous junction, and contaminates the reference element (Ag/AgCl). Our high-temperature sensors use polymerized solid electrolytes and pressurized chambers that prevent reference blow-out and resist thermal leaching.

Yes. Our high-temperature series is manufactured with FDA-compliant materials, non-cytotoxic polymer reference gels, and stainless steel (316L) or PEEK housing options. They meet sanitary requirements for upstream bioprocesses and clean-in-place (CIP) food processing applications.

As temperature changes, the Nernstian slope changes (from 59.16 mV/pH at 25°C to roughly 79.9 mV/pH at 130°C). By integrating high-accuracy Pt100 or Pt1000 RTD resistance elements directly beside the internal glass reference bulb, our transmitters dynamically adjust the Nernst calculation slope in real time, avoiding measurement drift.

Lifespan depends on cycle frequency and aggressive chemicals. Under standard biopharma SIP conditions (121°C for 30 minutes, 1-2 times per week), our specialized pH5806 series regularly maintains stability across 30 to 50+ steam sterilization cycles before recalibration slope limits drop below acceptable SOP thresholds (>90% slope).

We provide full private labeling, custom laser etching, customized insertion lengths, and preset digital addresses on Modbus RS485 systems. Standard express air shipments clear SFO international logistics centers reliably, with transit windows typically within 3 to 5 business days from our Shanghai manufacturing facility.
