Pro-Oceanus Systems Inc

Pro-Oceanus Systems is a leading designer and manufacturer of high-accuracy dissolved gas sensors for a wide range of scientific, commercial and industrial marine applications, including oceanography, environmental monitoring, and oil and gas. Designed to provide real-time monitoring and measurement of gases such as CO₂, CH₄ and TDGP, our innovative sensors deliver unparalleled reliability and stability under the most challenging of underwater conditions.

Our solutions have been provided to hundreds of clients in over 30 countries, and have been integrated into major national and international observing systems such as US Ocean Observatories Initiative, European Integrated Carbon Observing System, and Ocean Networks Canada.

Pro^TM Series

The Pro^TM Series is our highest-performing and most accurate range of dissolved gas sensors, using infrared detection technology to measure the partial pressure of CO₂ gas. The range includes options for deep-sea, buoy, and laboratory and benchtop deployments, offering long-term data stability for deployments of a year or more.

Pro^TM Series are ideal for a wide variety of applications including ocean acidification, MCDR, ships of opportunity, and air-sea flux studies.
