    • Rosemount™ 389/389VP General Purpose pH/ORP Sensors

    • Models 389 and 389VP are housed in a molded Tefzel® body with Viton® o-rings, making each sensor virtually indestructible and chemically resistant. Complete encapsulation eliminates leakage or high humidity problems traditionally found in other pH/ORP designs. The simplified construction, designed with user convenience in mind does not require electrolyte (KCl) replenishment or any high maintenance troubleshooting procedures.
