Rosemount™ 389-01-12-55: General Purpose pH/ORP Sensor for Tough Environments

  • Brand & Model: Rosemount™ 389-01-12-55 – a general purpose pH/ORP sensor.
  • Measurement Ranges: pH 0 to 14 and ORP -1500 to +1500 mV cover most industrial fluids.
  • Temperature Range: Operates from 32 to 185 °F (0 to 85 °C) for versatile use.
  • Automatic Temperature Compensation: Active from 32 to 185 °F (0 to 85 °C).
  • Triple Junction Reference: Resists poisoning ions like ammonia, chlorine, and sulfides.
  • Cracking Resistant Glass: Extends sensor life in harsh chemical environments.
  • ORP Electrode Material: Platinum provides stable oxidation reduction measurements.
  • Junction Type: Ceramic junction ensures consistent reference potential.
  • O-Ring Material: Viton® O-rings deliver superior chemical resistance.
  • Wetted Materials: Body and nut use polyester/polycarbonate; fittings are 316 stainless steel.
  • Process Connections: 1-in. MNPT front and rear facing for flexible mounting.
  • Sensor Thread: 1-in. NPT adapter for easy integration.

Easy Installation – Rosemount™ 389-01-12-55

  • Use the molded 1-in. MNPT threads for insertion, submersion, or flow-through setups.
