Back to Products

The CO2-Pro CV™ is a compact, lightweight, plug-n-play pCO2 sensor that is designed for use on moorings, on profilers, on ships in under-way mode, and in laboratories.

The CO2-Pro CV™ features the exceptional reliability, accuracy and stability of our famous CO2-Pro™, but open in a package that occupies less than half the volume.

The CO2-Pro CV™ instrument operates through rapid diffusion of gas from seawater through a new advanced matrix membrane to a non-dispersive infrared detector where pCO2 is measured.
