The CO2-Pro instrument measures the partial pressure of CO2 gas dissolved in water using infrared detection. Standard ranges from 0-600 ppm to 0-2000 ppm as well as custom ranges are available. This ensures the full spectrum of pCO2 is covered for accurate measurement of CO2 in any application.
With industry-leading pCO2 accuracy and stability for fully submersible instruments, the CO2-Pro sensor provides the reliable long-term data that are needed for monitoring and assessing the magnitude of ocean acidification, climate change, and carbon fluxes.
The patented supported tubular interface provides three effective modes of biofouling resistance: high shear on the membrane surface, darkness, and solid copper. The CO2-Pro is ideal for shallow waters in highly productive areas.
An internal zeroing feature provides a stable long-term baseline for ensuring accurate and stable measurements. The CO2-Pro can also be modified to measure both water and air pCO2.
For optimal accuracy, instruments are factory calibrated using WMO traceable standard gases. In addition, detector temperature stabilization and measurement of gas stream pressure and humidity provide accuracy unparalleled by other small submersible pCO2 instruments.
