pHalkon – pH monitor

Aquation’s pH monitor pHalkon (pH, alkaline, ocean) measures and records pH in seawater using an optical fluorescence technique.  pHalkon requires infrequent calibration and has relatively low and predictable drift.  pHalkon is insensitive to pressure, uses no electrolyte and withstands external pressures to 5 bar/50 m depth (or more with a special housing).
