385 pH/ORP Sensor

Brand: Rosemount
Request Information
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.
Features
  • 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
