Measuring dissolved material load to assess water quality, purity, and process suitability.
A TDS sensor measures the total concentration of dissolved substances in a liquid, typically expressed in mg/L or ppm. These dissolved solids include salts, minerals, metals, and organic compounds that affect water usability, treatment efficiency, and product quality.
TDS sensors do not measure dissolved solids directly. Instead, they estimate TDS by measuring electrical conductivity and applying a conversion factor. The relationship between conductivity and TDS depends on the composition of dissolved ions.
The measured value directly represents the estimated concentration of dissolved solids in a liquid.
TDS trends indirectly indicate water purity, membrane performance, scaling and fouling risks, salinity changes, and suitability of water for specific processes.
With Industrial IoT integration, TDS sensors enable continuous monitoring of water quality, automated membrane system control, early detection of contamination, and long-term compliance documentation.
The TDS Sensor translates dissolved content into clarity. By quantifying what cannot be seen, it supports water quality assurance, process reliability, and sustainable resource management across industries.
