Profile: Sunburst Sensors, LLC manufactures Sami™ autonomous chemical sensors. Our Sami™ autonomous chemical sensor uses a patented colorimetric method for in-situ measurement of chemical species in aquatic environments. We specialize in instruments that measure inorganic carbon parameters pCO2, pH and total alkalinity. Our Sami-CO2 is a reagent based sensor for measuring partial pressure of carbon dioxide (pCO2) in water over a range of approximately 0-2000 µatm with a precision of ~ 1 µ atm @ 360 µ atm.
