[Ryan] designed a PCB that lets you easily take readings from a commercial electrical conductivity probe over I2C. Conductivity measurements are great for measuring the salinity of a solution, which ...

Coastal salinity is an increasing challenge in low-lying agricultural landscapes. Saltwater inundation (SWI) from tidal flooding can create obvious dead zones along field edges, but these visible ...

Researchers have demonstrated that electrical conductivity can be an effective means to precisely measure the amount of blood present in dry blood spot analysis, providing a new alternative to the ...

IN NATURE of Mar. 21, p. 441, M. Lecomte du Noüy outlines improvements in the method commonly used to measure the electrical conductivity of electrolytes. We are particularly interested in this ...

Some of the most revealing signals about human health are carried in fluids that are almost impossible to measure. Tears, ...
