This is the new (beta) Inline Rich Wikis system. Use the "pencil" buttons after different paragraphs to edit inline, and report problems here

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

Also see resources on this page:


Ask a question  or help answer future questions on this topic


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 for people to test methods (these develop over time)

Add an activity  or request an activity guide you don't see listed

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