Model SAMI-pH -Ocean pH Sensor

Measures pHT (total hydrogen scale) in the marine pH range of 7-9, Uses a highly accurate colorimetric reagent method, System does not suffer from the drift that plagues most electrode based pH probes, Designed to provide researchers with valuable in-situ time series data at depths up to 600 meters, 234-day deployment capability (hourly measurements, 25C), Extra battery package allows the SAMI-pH to run for more than a year, Can support up to 3 external instruments (e.g., PAR, dissolved oxygen, chlorophyll fluorometer, CTD), Supports Seabird underwater inductive modems or external loggers via RS-232
