Without any salts, water is actually a very poor conductor of electricity. However, most of the salts that make water conductive are also nutrients and/or human-applied. If you want to measure these salts, then, what you need to do is measure the conductivity of the water you’re working with. While this module and probe won’t tell you whether you’re dealing with chloride*, nitrate, sulfate, phosphate, or other types of salts, it will tell you what their total population is in a number that’s linked to Total Dissolved Solids, or TDS.

The conductivity module board connects with a conductivity probe by way of a SMC connector. This probe is rated for full immersion up to the end of the cable, and can operate over a broad range of temperatures. Conductivity calibration standard solutions not included.
