Adwa EC Tester Waterproof AD31

Waterproof, pocket-sized, digital conductivity meter “Adwa EC/TDS AD31”

Electrical conductivity or the conductance depends on the amount and valence of the ions in the solution. Based on this information, we can estimate the amount of fertilizers in the growing medium.
