385+ General-Purpose pH/ORP Sensor

Brand: Rosemount
The Rosemount 385+ pH/ORP combination sensors are used for reliable pH or oxidation/reduction potential measurements of aqueous solutions in pipelines, open tanks, or ponds.

Rosemount 385+ sensors feature a triple junction reference that extends sensor life in processes containing poisoning ions.
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
