Tds Meter Circuit. So a PPM/TDS meter is a EC meter that converts the EC value into PPM values There are alot of descriptions online about why and how to measure PPM/TDS or EC so google for them if you want alot more details EC is a measure of Electrical Conductivity from two probes 1cm apart 1 EC is = 1 microsiemens to convert from EC to siemens multiply by 1E6.

What Is a TDS Meter? How to Test & What it Measures in
TDS Meter with TDS Sensor and Arduino for water quality monitoring in Realtime Total dissolved solids (TDS) are measured in milligrams per unit volume of water (mg / l) or also referred to as parts per million (ppm) For drinking water the maximum concentration level established by the EPA (the United States Environmental Protection Agency) is 500 mg / L.

EC/TDS/PPM Meter
TDS meters measure the electrical conductivity of water Pure water is a poor conductor but total dissolved solids carry a distinct electrical charge that correlates directly to TDS levels The greater the charge — the higher the level of dissolved solids It’s the quickest way to get a feel of what in your water.
