Product No.:202312219856

  • Details

Rosemount Analytical Model 3900 pH/ORP Sensor.



Features

  • SMART enabled
  • Available in hemi bulb, flat bulb, HF resistant, and Hi pH glass
  • Special features for processes with low conductivity, hydrofluoric acid, high pH, and reference poisoning elements
  • Watertight VP8 multiple-pin connector available which eliminates cable twisting.
  • Double or triple junction reference cell
  • Various mounting options
  • Sealed PPS body provides maximum protection


The Rosemount Analytical 3900 and 3900VP General purpose pH/ORP sensor models are provided with a double junction reference, which protects the reference element from poisoning ions – such as ammonia, chlorine, cyanides, and sulfides – in the process. The double junction reference aids in the sensor's resistance to harsh environments and helps prolong sensor life. Both models are made with porous Teflon® junction positioned near the pH/ORP-sensitive membrane.

Model 3900VP is offered with a watertight sensor-to-cable connector which eliminates re-wiring and cable twisting when replacing sensors. The Variopol VP multiple pin connector is an integral part of each sensor model and uses a mating VP cable. Once the cable is installed and wired to the analyzer, sensors are easily replaced without replacing the cable and without rewiring the analyzer. Also the cable can be disconnected from the sensor before removal from the process which eliminates cable twisting.

Models 3900 and 3900VP are housed in a molded PPS body, making each sensor virtually indestructible and chemically resistant. Complete encapsulation eliminates leakage or high humidity problems traditionally found in other pH/ORP designs. The simplified construction, designed with user convenience in mind does not require electrolyte (KCl) replenishment or any high maintenance troubleshooting procedures.

Both models are combination sensors (pH, reference, and temperature within sensor body) and measure pH or ORP (Oxidation/Reduction Potential) of aqueous solutions in pipelines, open tanks, or ponds. Models 3900 and 3900VP are suitable for virtually all applications and are compatible with Rosemount Analytical and other manufacturers' instruments.
