Instrument: pH Sensor

Dataset: 
juvenile coral calcification
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: pH Sensor
Dataset-specific description

The pH (NBS) of the aquaria during all experiments was checked twice weekly using an Orion 3-star pH meter and calibrated electrode; the precision of replicate pH measurements was +/- 0.015 units.
