"An in situ total hydrogen scale pH sensor used to measure seawater pH. It is designed to provide seawater pH time-series data for scientific research at depths up to 600 metres. It can support 3 external instruments such as PAR, dissolved oxygen, fluorometer, or CTD. It also supports Seabird inductive modems or external loggers via RS-232. It has 234-day deployment (~4300 measurement) capability, providing hourly measurements, and can be fitted with an extra battery to extend deployment duration to over a year. The SAMI2-pH sensor operates in the pH range of 7-9 and the salinity range of 30-36. It has a precision <0.001 pH units and an accuracy +/- 0.003 pH units." . "Sunburst SAMI2-pH" .
