Model 385/385+ pH/ORP Insertion and Retractable Sensors
The Rosemount 385 Retractable pH/ORP Sensor is designed to meet a wide variety of industrial applications. It has been specially designed for applications where the process cannot be shut down and a separate sample stream is difficult or impossible to provide. The 385 body is constructed with a standard titanium tube and Tefzel, allowing the sensor to be used in especially harsh applications such as bleach lines in paper mills.
- RETRACTABLE OPTIONS allow sensors to be easily removed and replaced under pressure without process shutdown.
- MAXIMUM CHEMICAL RESISTANCE with a disposable Tefzel and titanium design
- INTEGRAL PREAMPLIFIER provides noise free, long distance transmission of the high impedance pH signal.
- POISONING RESISTANT triple junction reference electrode
