CO2-Pro - Model CV -Submersible pCO2 Sensor

The most versatile and accurate submersible sensor for monitoring pCO2, our flagship model is deployed on moorings, profilers and underway in studies of the near surface to the deep ocean.

With industry-leading pCO₂ accuracy and stability for submersible instruments, the CO₂-Pro™ CV is the sensor of choice for most applications. Labelled the CV for Compact Version of our flagship CO₂-Pro™ instrument, the Pro™-CV can be deployed to 6000 meters depth, ideal for carbon capture storage monitoring and deep ocean CO₂ fluxes.

The small size of the CO₂-Pro™ CV means it is easily transported and deployed in the field. When combined with our anti-fouling features and options, the instrument can perform in even the most biologically active rivers and lakes for extended periods of time. An internal zeroing feature provides a stable long-term baseline to ensure accurate measurements. A flow-through adapter is also available for simple integration into many systems. The CO₂-Pro™ CV is factory calibrated using WMO traceable standard gases. In addition, detector temperature stabilization and measurement of gas steam pressure and humidity provide accuracy unparalleled by other small submersible pCO₂ instruments.
