Rosemount 3900VP-01-10 3900 General Purpose pH/ORP Sensor with Variopol (VP) Connection
The Rosemount 3900VP General Purpose pH Sensor / ORP Sensor features a double junction reference that aids in the pH/ORP sensor's resistance to harsh environments and helps prolong sensor life. The double junction protects the reference element from poisoning ions - such as ammonia, chlorine, cyanides, and sulfides. The pH/ORP sensor is made with a porous Teflon® junction. The robust pH/ORP sensor design makes the Rosemount 3900VP pH/ORP Sensor a reliable choice for a wide range of aqueous solutions found in pipelines, open tanks or ponds.
