CO2-Pro™ CV Submersible pCO2 Sensor

The CO2-Pro™ CV instrument measures the partial pressure of CO2 gas dissolved in water using infrared detection. Standard ranges from 0-600 ppm up to 0 - 10,000 ppm as well as custom ranges are available that cover the full spectrum of pCO2 needed for accurate measurement of ocean, coastal, riverine, and lake CO2 levels.

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.
