SAMI-pH
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.
