Instrument: pH Sensor

Dataset: 
OA and temp expt. - water chemistry
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: accuFet Solid-State pH probe (Fisher Scientific Waltham, Massachusetts, USA)
Dataset-specific description

The pH probe was calibrated with 7.00 and 10.01 NBS buffers which were kept at experimental temperatures; used to measure pH.
