| Definition | An in situ self-contained chemical sensor designed by the University of Minnesota to conduct real-time pH measurement of the aquatic environment, specifically deep-sea hydrothermal vent fluids. It primarily measures temperature, pH and redox and is fully automated. The electrochemical response of the sensor system is based on Yittria-stabilized zirconia (YSZ) ceramic membrane electrode with an internal Ag-AgCl reference electrode pair (Hg/HgO). This instrument is capable of measuring pH of hydrothermal vent fluids in temperatures up to 300 degC. |
