Alkalinity Sensor

In-Situ Monitoring of Total Alkalinity

Dartmouth Ocean Technologies introduces a miniaturized, autonomous alkalinity sensor for marine environments that will enable Ocean Alkalinity Enhancement (OAE) and monitor the ocean’s buffering capacity.

Alkalinity Sensor at a Glance:

  • Accurate measurement of microfluidic alkalinity over the range 1500-2500 µmol / kg
  • Measurement calibrations against certified reference materials
  • Programmable sample rate and concentration range
  • Technology Flexibility: An excellent contender for towed systems, un-crewed vehicles, gliders, ROVs, Voluntary Observation Ships, buoys, and profiling floats
  • Customizable and configurable to fit into most platforms


  • Alkalinity Sensor
  • Rigid Reagent Housing
  • Self-Contained
  • 275 samples / 25 standards per reagent load*
  • Programmable sample interval & range
  • Easy transport and deployment
  • Flexible mounting configurations


  • Optional power from platform or battery pack
  • Dual- and Tri-case mounting brackets
