Rosemount™ 3300HT High Performance pH and ORP Sensor
Rosemount 3300HTVP & 3300HT pH/ORP Sensor
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.
