Dartmouth Ocean: Phosphate Sensor

The A1000-200 Phosphate Sensor is an Ortho Phosphate sensor “Inlaid Optical Cell Technology“. This innovative microfluidic wet-chemistry sensor provides real-time measurement of phosphate concentration. The sensor is self-powered and self-logging. Deployment duration is a function of logging rates and battery selection.

In-Situ Nutrient Detection

Cost Effective Solution to Real-Time Measurement of Phosphate Concentration

Lab-on-Chip (LOC)

Microfluidic wet-chemistry sensor featuring patented and proprietary “Inlaid Optical Cell Technology™”. Reduces reagent consumption, decreases reaction time, and reduces power draw.

Self-Powered/Self-Logging

Self-powered and self-logging for real time measurement.

Technology Flexibility

This sensor is an excellent contender for towed systems, uncrewed vehicles, gliders, ROVs, Voluntary Observation Ships, buoys, and profiling floats.

Customizable

The sensor is configurable and can be customized to fit into most platforms.
