Rosemount™ 396P pH/ORP Sensor
Rosemount 396P and 396PVP pH/ORP sensor
The Rosemount 396P pH Sensor/ORP Sensor, with integral cable, is specifically designed for improved life in harsh, dirty, and abrasive applications such as lime slurry waste treatment, paper machine headbox and pigment/dye applications, where large quantities of suspended solids are present.
The pH/ORP sensor features a coating resistant TUpH large area reference junction and a rugged polypropylene body construction for maximum chemical resistance.

Rosemount™ 396P pH/ORP Sensor


Measurement Range
pH sensor: 0 to 14
ORP sensor: -1500 to 1500 mV
Operating Pressure
Hemi-bulb: 0 to 150 psig (0 to 10.34 barg)
Flat-bulb: 0 to 100 psig (0 to 6.89 barg)
Operating Temperature
32 - 212 °F (0 -100 °C)

  • Minimum pH/ORP sensor maintenance due to TUpH reference technology which ensures steady pH signal when sensor is coated
  • Maximum pH/ORP sensor life due to helical reference pathway which hinders reference poisoning and cracking resistant glass
  • SMART enabled for pH measurements
