Rosemount™ 389 General Purpose pH/ORP Sensor

Product Description

The Rosemount 389 pH Sensor / ORP Sensor, with integral cable, is 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 sensor designs. The simplified construction, designed with user convenience in mind, does not require electrolyte (KCl) replenishment or any high maintenance troubleshooting procedures
