Overview
A Robust Sensor Design
Operates in low conductivity water down to 0.4 µS/cm.
High signal stability with flowing reference electrode and
laser drilled capillary junction.
Operates in sample temperatures of 0 to 70 °C (32 to
158 °F).
Built-in solution ground for measurement stability and
complete diagnostic functionality.
Ease of Installation and Maintenance
Rosemount 3200HP features a complete panel mounted
system, including an electrolyte reservoir, a flow cell, a pH
sensor, and a calibration cup holder.
Contents
Easy to replace liquid junction and refillable electrolyte
reservoir.
Variopol (VP8) cable connection option, for quick cable-
to-sensor release, which eliminates cable twisting.
