Measuring TDS of Filtered Tap Water: An Amateur Scientist's Guide

AI Thread Summary
To measure the total dissolved solids (TDS) of filtered tap water, low voltage AC is typically used for electrical conductivity (EC) measurements. Various methods exist for conducting these measurements, and resources like specific PDFs can provide foundational knowledge. Understanding the voltage potential involved is crucial for accurate readings. The discussion emphasizes the importance of researching water conductivity measurement circuits for practical applications. This approach aids amateur scientists in effectively assessing water quality.

I am an amateur scientist interested in all fields of science.
What voltage potential is used to measure the EC of water to approximate TDS of filtered tap water?
 
Physics news on Phys.org
Do a search on "water conductivity measurement circuit".
There are several ways to go about it, although usually low voltage AC is used.
This PDF goes over the basics. https://www.instmc.org/Portals/0/Tech%20Talk%20%2810%29%20Liquid%20Conductivity%20Measurement.pdf

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
