Understanding EC and TDS Measurements
Electrical Conductivity (EC) measures the ability of water to conduct electricity, which correlates directly to the concentration of dissolved salts and minerals. Total Dissolved Solids (TDS) represents the total concentration of dissolved substances in water. The LSM-100 provides both measurements, allowing you to monitor water quality in the units most relevant to your application.
