Welcome to Sunburst Sensors, LLC


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 next generation of pCO2 and pH sensors is now available. With improved reliability, durability and user-friendliness, the SAMI supports up to three additional sensors and can be deployed to depths of up to 600 m.
