Rosemount™ 3300HT High Performance pH and ORP Sensor

Withstands high temperature and pressure, resists fouling and poisoning, providing quicker response and reduced drift, minimizing sensor replacement frequency.

The Rosemount™ 3300HT pH/ORP sensor is engineered to keep your process on spec where conventional probes fall short, delivering stable, accurate pH or oxidation reduction potential (ORP) readings in hot, pressurized, and chemically aggressive applications through its PERpH X™ high performance platform. Its durable, rebuildable reference design lowers total cost of ownership by allowing you to refresh electrolyte and return the sensor to service instead of replacing it—reducing spares, service time, and lifecycle cost. Application specific electrolyte options ensure stability across challenging processes, while reduced drift and refillable electrolyte designs keep maintenance low.

Key Features

  • Increased pH sensor / ORP sensor life and performance in high temperature and high pressure applications up to 155 °C and 400 psig
  • SMART preamplifier allows automatic recognition of pH sensors by Rosemount 1066, 1057, 1056 and 56 transmitters
  • Selectable reference electrolytes allow sensors to be used in a large number of applications
