From year-long deployments in the Arctic, to shipboard transects underway, to diver held sensors on coral reefs, Pro-Oceanus submersible dissolved CO2, CH4 and total dissolved gas pressure sensors are deployed on a wide range of platforms, in all the World’s Oceans, in costal zones, and in lakes and rivers. Need something different? We will work with you to develop unique custom solutions.

Our compact submersible sensors measure dissolved CO2, CH4 and total dissolved gas pressure in ground waters, detect hydrocarbon leaks in subsea pipelines, monitor effluents and even measure gas buildup in African “killer” lakes. Contact us to help design a solution for your gas measurement needs.

Through monitoring in aquaculture, detection of leaks, and measurements in process vessels, effluents and feedstocks, Pro-Oceanus dissolved gas sensors reduce operating costs and improve quality control. Our sensors work in water, oil and air, and are available with resistances to a broad range of chemicals. Contact us for innovative solutions to your gas measurement challenges.

Proud to provide world-class technology in dissolved gas sensors for 20 years
