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: handheld pH probe
Dataset-specific description
Target pH levels were monitored daily using a handheld pH probes (Orion Ross Ultra pH/ATC Triode with Orion Star A121 pH Portable Meter; Intellical PHC281 pH Electrode with Hach HQ11D Handheld pH/ORP Meter) calibrated bi-weekly with 2-point pHNBS references.
