Introduction to Pro Oceanus Canada:

Canadian Pro Oceanus Systems (PSI, website www.pro Oceanus. com) was founded in 1998 by two marine scientists, Dr Bruce D. Johnson and Dr Founded by Craig L. McNeil, located in Nova Scotia, Canada, where marine research units are concentrated. PSI manufactures the world's most advanced high-precision and high stability on-site underwater dissolved gas measuring instruments.

Before the founder of PSI successfully developed the first GTD Pro, the method for measuring dissolved gases in seawater was to collect water samples and analyze them in the laboratory. This method could no longer meet the needs of modern ocean research because scientists had turned to research methods such as anchor systems (buoys or submersible markers) and observation platforms, which required continuous work in the sea for 6 months to a year, and there was no time for on-site calibration. PSI founder Dr Johnson was the overall leader of the Canadian Joint Global Ocean Flux Study at that time. At that time, there was no established method for measuring seawater carbon absorption because such measurement techniques did not exist. Faced with the challenge of sampling requirements, PSI has launched cutting-edge research work with the aim of providing highly stable and accurate dissolved gas probes for marine research and environmental monitoring. They have successfully developed CO2 Pro underwater carbon dioxide meters and GTD Pro underwater total dissolved gas pressure meters, which are protected by patented technology. Suitable for on-site observation, navigation measurement, anchoring (buoy or submersible) measuring instruments, etc. Becoming the most widely used instrument in the field of marine and gas research, it is welcomed by researchers.

Mini CH4 ™ Introduction:

Mini CH4 from Pro Oceanus Canada ™ The miniature underwater methane measuring instrument is a world leading instrument for measuring underwater methane concentration. It is compact, lightweight, plug and play, requires minimal maintenance, has low power consumption, and has low maintenance costs.

Mini CH4 ™ The miniature underwater methane measuring instrument adopts rapid membrane permeation equilibrium measurement technology, which reaches the infrared detector inside the instrument through an advanced oil resistant substrate membrane for measurement without the need for chemical reagents. The instrument is not affected by biological attachment and can remain stable for a long time even in rivers and lakes with severe biological attachment.

Mini CH4 ™ The miniature underwater methane measuring instrument can simultaneously measure the total dissolved gas pressure (TDGP) parameter and measure the concentration of CH4 in water, oil, and oil-water mixtures. Widely used in natural gas hydrate research, underwater pipeline detection, water pollution detection, oil and gas leakage and diffusion monitoring, anaerobic environment research, wastewater greenhouse gas emissions and other fields. It can also be conveniently integrated onto underwater ROVs for underwater detection.

The instrument with a titanium alloy casing can be deployed to a depth of 4000m for the collection and storage of CH4 concentration.
