dissolved CO2 deep sea sensor
The CO2-Pro™ is a lightweight, compact, and versatile sensor for measuring the partial pressure of CO2 in water. It is designed for in-situ pCO2 measurement on shipboard in underway-mode, in the laboratory and on moorings, profilers and gliders.
The CO2-Pro™ is a versatile pCO2 instrument featuring the Pro-Oceanus patented pump-driven tubular gas transfer interface.This revolutionary interface provides rapid equilibration of surrounding water with a NDIR detector.
Long-term stability is achieved with the CO2-Pro™ sensor through an automatic zero compensation circuit that removes all CO2 from the detector prior to a zero reference measurement. The CO2-Pro™ dissolved CO2 instrument comes with plug-n-play ease of operation, and a range of data handling options including storage onboard, and continuous or pollable output.
