Rosemount™ 3500P pH/ORP Sensor
Rosemount 3500VP & 3500 pH/ORP sensor
The Rosemount 3500P pH / ORP Sensor, with integral cable, incorporates several design innovations that prolong the life of the sensor in difficult applications.
The pH/ORP sensor features a rebuildable double junction reference cell that allows for wide application flexibility by using different reference electrolyte solutions. The resulting sensors live longer, respond faster and drift less thereby minimizing maintenance and lowering the total cost of ownership.
