The Rosemount Analytical Model 396R / 396RVP pH/ORP Sensor is specifically designed for improved life in harsh, dirty applications where a separate sample stream is difficult to provide and greater insertion depths are required. It is designed for use with a1-1/4 in. or 1-1/2 in. ball valve for hot tap installation.

The Model 396R is constructed of molded polypropylene housed in a titanium tube with EPDM seals to provide maximum chemical resistance. The sensor also features a titanium solution ground for advanced sensor diagnostics when used with the Model 54 or Model 3081 pH/ORP Analyzer/Transmitter. These advanced sensor diagnostics provide preventative maintenance by notifying the operator of the need for replacement and cleaning of an aged or fouled sensor, thus allowing continuous optimum performance.

The Models 396RVP ball valve retractable sensor features a gel-filled electrolyte solution with the large area, coating resistant TUpH reference junction in a polypropylene material and a standard hemi or optional flat glass bulb. It is housed in a Titanium sensor tube and can be mounted directly into the process using a 1 in. MNPT threaded process connector and a ball valve assembly kit (ordered separately). It is offered with the watertight Variopol sensor-tocable connector and use the mating connector cable (ordered separately). VP8 cable assembly works with VP6 and VP8 sensor connector. The 396R is SMART enabled. Option (-70) is the standard preamplifier option. Also available is a choice of temperature element, 3 K Balco or Pt 100 RTD. VP8 cable is required for SMART communication.

The sensor also features a slotted tip for protection from breakage while allowing the process to flow by the glass electrode for accurate and reliable pH measurement.

The Model 396R is only available without an integral preamplifier and has 15 ft or 9.5 in. of integral high quality 9 conductor cable. The preamplifier must be housed in a remote location or in a junction box kit for attachment at the rear, cable end of the sensor (order separately) or must be integral to the Analyzer/Transmitter. The Model 396R is compatible with all Rosemount Analytical and other manufacturers' instruments.
