mini dissolved CO2 sensor

CO2 SensorThe Pro-Oceanus Mini-Pro CO2™ is a low-cost, compact, lightweight, plug-n-play pCO2 sensor designed for use in groundwater, boreholes, aquaculture, algae-to-biofuels, aquaculture, carbon sequestration, marine and freshwater research, and for general monitoring in oceanographic applications. The sensor can even be used in soil or borehole applications.

The Mini-Pro CO2™ probe is designed to measure dissolved CO2 in applications involving immersion in water, oil, or water and oil mixtures.

The Mini-Pro CO2™ probe operates through rapid diffusion of gas from liquid through an oil resistant, advanced matrix interface (patent pending) to a non-dispersive infrared detector. The signal is compensated for both pressure and temperature.
