Pro-Oceanus Systems Inc. products

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. 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.

The CO2-Pro™ Atmosphere instrument measures the partial pressure of CO2 gas in both surface water and air for accurate determination of CO2 flux. An internal zeroing feature provides drift correction for stable and accurate long-term measurements. Designed for use on buoys, the rugged unit is comprised of a CO2-Pro™ that mounts under the buoy for water measurement connected to a NEMA box that is used to take in air from above the buoy. Alternating measurements of pCO2 in air and water provide accurate data for reliable surface flux calculations. The instrument is well-suited for integration into shipboard flow-through systems.

Designed for continuous benchtop monitoring of CO2 on ships and in laboratories. The CO2-Pro™ FT instrument measures the partial pressure of CO2 gas dissolved in water using infrared detection. Standard ranges from 0-600 ppm up to 0 - 2,000 ppm, along with custom ranges, provide the full spectrum of pCO2 needed for accurate measurement of water CO2 levels.

The GTD-Pro™ is the most accurate and stable total dissolved gas sensor on the market. It measures the sum of the partial pressures of all dissolved gases, i.e. gas tension. In most natural waters N2 and O2 are the dominant dissolved gases. When oxygen is measured independently, N2 can be determined from gas tension. These gases measured together can be used to make substantially improved estimates of net biological production. Additionally, gas tension measurements are used to study air-sea gas exchange and upper-ocean physical, chemical, and biological processes. Also available is the HGTD-Pro™ hurricane model that uses a patented supported tubular interface for faster equilibration than the GTD-Pro™.
