Instrument: pH Sensor

Dataset: 
Moorings - Temp Sal O2 pH
Instrument: 
pH Sensor
Instrument Short Name: pH Sensor
Instrument Description:

An instrument that measures the hydrogen ion activity in solutions.

The overall concentration of hydrogen ions is inversely related to its pH.  The pH scale ranges from 0 to 14 and indicates whether acidic (more H+) or basic (less H+). 

PI supplied instrument name: Honeywell Durafet III pH sensor
Dataset-specific description

The SeapHOx consists of a Honeywell Durafet III pH sensor (Martz et al. 2010), an Aanderaa 3835 oxygen optode, and an SBE-37 MicroCAT CTD. The sensors were attached to a mooring line at a given water depth below the surface (e.g. 7 m).
