Rosemount™ 385+ General Purpose pH/ORP Sensor
The Rosemount 385+ Retractable pH Sensor / ORP sensor can support a wide variety of industrial applications. It's designed for applications where the process cannot be shut down and a separate sample stream is difficult or impossible to provide. The pH/ORP sensor body is constructed with a standard titanium tube and Tefzel™, allowing the sensor to be used in harsh applications such as bleach lines in paper mills.
