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.

GTD-Pro ™ Introduction:
GTD Pro from Pro Oceanus Canada ™ The small underwater total dissolved gas measuring instrument is currently the most accurate and stable total dissolved gas measuring instrument on the market. In most natural waters, nitrogen and oxygen are the main dissolved gases. When oxygen is measured separately, nitrogen can be calculated from the gas tension value. The measurement of these gases can be used to fully evaluate net biomass production.
In addition, gas tension measurement can be used to study the physical, chemical, and biological processes of air sea exchange and upper seawater.
There are two models of underwater total dissolved gas pressure measuring instruments: the standard GTD Pro and the hurricane HGTD Pro. The main difference between the two is that the HGTD Pro model is much smaller in size and weight, and adopts a patented water pump driven fast balancing measurement interface, with a faster balancing speed than the GTD Pro.

GTD-Pro ™ Main features:
1. Measure the total dissolved gas pressure
2. High precision, long-term stability;
3. Can be applied to anchor observation, underwater observation network, submersible markers, navigation observation, and laboratory measurement;
4. Hurricane type instruments have a fast response rate;
5. Easy to integrate into other systems;
6. No need to use expensive calibration gases;
7. Not affected by biological attachment, with good long-term stability and low maintenance costs;
