| Definition | A series of in situ total hydrogen scale pH sensors used to measure freshwater or seawater pH. They are designed to provide autonomous pH time-series data for scientific research. The sensors operate by mixing sample with an indicator dye and measuring pH by absorbance. Typical dyes are cresol red for freshwater or m-cresol purple for seawater samples. Light sources and path lengths vary between versions (tungsten, LEDs) Accuracy ranges between -0.003 to + 0.0004 pH units. Precision ranges from +/-0.004 to +/-0.0007 pH units. This code is used where it is not known which version of SAMI-pH model is used. | ||
