We design and manufacture autonomous instruments that measure the marine and freshwater inorganic carbon parameters pCO2 (partial pressure of carbon dioxide) and pH using our patented drift-free technology.
The SAMI ™ – Submersible Autonomous Moored Instrument – measures and logs pH or pCO2 in marine and freshwater environments over long periods with ultra-low power and reagent consumption, providing valuable time-series data to researchers around the world. The AFT - Autonomous Flow Through - uses the same technology for flow through measurements on research vessels or on the bench-top. Our SuperCO2 systems are designed for high frequency pCO2 measurements from a sample stream using either a showerhead equilibrator or contactor.
Sunburst Sensors is proud to have won both purses of the Wendy Schmidt Ocean Health XPRIZE using instruments based on our SAMI technology. Read about it in Sunburst News. We are now selling the 'iSAMI-pH' and 'πSAMI-pH' systems based on the technology that won the 'affordability purse'. Read more about it here and here.
Our pCO2 and pH sensors are available for your next research project. Combining reliability, durability and user-friendliness, the SAMI supports up to three additional sensors and can be deployed to depths of up to 600 m.
