The Rosemount 3900 pH Sensor / ORP Sensor features a double junction reference that aids in the sensors' 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. Both sensors are made with a porous Teflon® junction. The robust ph/ORP sensor design provides reliability in a wide range of aqueous solutions found in pipelines, open tanks or ponds.
