3500P/3500VP PERpH-X pH/ORP Sensor

Brand: Rosemount
Request Information
Rosemount 3500P/3500VP PERpH-X™ pH / ORP sensors incorporate several design innovations that prolong the life of the sensor in difficult applications. 

The sensors feature 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.
Features
  • Rebuildable design allows sensor use in applications of elevated temperatures, fouling, coating and poisoning
  • Fast, accurate, and stable measurement
  • SMART enabled for pH measurements
