Instrument: Benchtop pH Meter

Instrument Short Name: Benchtop pH Meter
Instrument Description:

An instrument consisting of an electronic voltmeter and pH-responsive electrode that gives a direct conversion of voltage differences to differences of pH at the measurement temperature. (McGraw-Hill Dictionary of Scientific and Technical Terms)

This instrument does not map to the NERC instrument vocabulary term for 'pH Sensor' which measures values in the water column. Benchtop models are typically employed for stationary lab applications.

PI supplied instrument name: pH Probe
Dataset-specific description

A Thermo-Orion ROSS 8165BNWP electrode, read to 0.1 mV, was used to measure the pH of each experimental container.
