Rosemount 3900 General Purpose pH/ORP Sensor UK & Ireland

Rosemount 3900 General Purpose pH/ORP Sensor

The Rosemount 3900 pH/ORP combination sensor’s double junction reference aids in the 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 sulphides. Both sensors are made with a porous Teflon® junction. The robust sensor design makes the 3900 reliable in a wide range of aqueous solutions found in pipelines, open tanks or ponds.
