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

Click For Summary
SUMMARY

This discussion focuses on measuring the Total Dissolved Solids (TDS) of filtered tap water through electrical conductivity (EC) measurement. It is established that low voltage AC is typically used for this purpose. The conversation references a specific resource, a PDF document from the Institute of Measurement and Control, which provides foundational knowledge on liquid conductivity measurement. This resource is essential for understanding the principles behind TDS measurement in water.

PREREQUISITES
  • Understanding of electrical conductivity measurement techniques
  • Familiarity with low voltage AC circuits
  • Knowledge of TDS and its significance in water quality
  • Basic skills in interpreting scientific literature and technical documents
NEXT STEPS
  • Research "water conductivity measurement circuit" for practical applications
  • Study the PDF on liquid conductivity measurement for in-depth knowledge
  • Explore TDS meter calibration techniques for accurate readings
  • Investigate the impact of different water sources on TDS levels
USEFUL FOR

This discussion is beneficial for amateur scientists, environmental enthusiasts, and anyone interested in water quality analysis and measurement techniques.

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
