Water conductivity monitoring



Conductivity is a measure of a solution's ability to conduct electricity, as measured in Siemens per meter (S/m).

This page is under development, please add background info:

  • Info about regulations
  • Info about ecological or human health impacts
  • Advocacy leverage points
  • Constraints we're working within: cost, complexity, sensitivity, time
