500ms/cm Digital Graphite 4 Pole Conductivity TDS Salinity Sensor with 0-60℃ Temperature Range and IP68 Rating
This digital conductivity sensor measures the electrical conductivity of water solutions to determine total dissolved solids (TDS), salinity, and electrolyte concentration. When electrodes are inserted into water and electricity is applied, dissolved ions migrate under the electric field, enabling conductivity measurement. This parameter serves as a crucial water quality indicator, reflecting the presence of electrolytes and dissolved salts. Conductivity varies with temperature and electrolyte concentration, with lower conductivity indicating purer water.
- Reagent-free operation for pollution-free, economical, and environmentally friendly measurement
- Durable electrode construction using 316L+POM and PP+ABS materials
- High-quality dedicated sensor cables for accurate and stable signal transmission
