Welcome to Sunburst Sensors, LLC

We design and manufacture autonomous instruments that measure the marine and freshwater inorganic carbon parameters pCO₂ and pH using our patented drift-free technology.

The SAMI ™ – Submersible Autonomous Moored Instrument – measures and logs pH or pCO₂ over long periods with ultralow 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.
