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

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

Questions



Sensors

Here's a list of different conductivity sensors and measurement systems. Also see below for some Do-It-Yourself approaches to measuring conductivity, and this page for more information.


Activities

Activities for people to test methods (these develop over time)


Activities should include a materials list, costs and a step-by-step guide to construction with photos. Learn what makes a good activity here.
