©2020 Biological and Chemical Oceanography Data Management Office.The Unisense pH microelectrode is a miniaturized conventional pH electrode. The instrument is designed for research applications. It is based on selective diffusion of protons through pH glass, and the determination of potentials between the internal electrolyte and an internal or external reference electrode. It has a range of tip sizes (10 um-1.1 mm), a measurement range of pH 2-10 (linear 4-9) and detection limit of 0.1 pH unit. See more on the manufacturer's website: https://www.unisense.com/

|---|---|---|
| pH from microsensor profiles of ex situ sediment cores collected in the Chesapeake Bay and measured during 2017-2018 | Unisense A.S. microsensors (Denmark) and motorized micromanipulator system were used for data collection. The 4 channel microsensor multimeter was used, with the following microsensors: Ox-50, pH-200, and H2S-100. Each sensor was used consecutively. | Unisense A.S. microsensors (Denmark) |
