The pCO2 sensor provides very precise autonomous measurements based on a spectrophotometry approach regarding the pCO2 concentration. The sensor can be integrated on CARIOCA and PIRATA buoys with the aim to measure CO2 partial at the sea surface of ocean and also determine the AIR-SEA CO2 fluxes in open ocean.

 Autonomous measurement based on spectrophotometry

 High accuracy & Low drift

 Optional datalogger mode with satellite transmission
