Conductivity TDS Meters

Conductivity TDS Meters

Electrical Conductivity (EC) / TDS Meters

Conductivity meters measure the number of ions mobile within a liquid, the most accurate way of determining the salinity of a soil.  Plants take in nutrients in ion form (ie nitrogen, phosphorus, and potassium ions (NPK)), and the total amount of ions in a soil solution can indicate potential nutrients available to them (although not specific nutrients).

EC meters can also be used to:

  • determine the quality of water.
  • test and standardize concentration of liquid fertilizers in spray bottles.
  • test the maturity and quality of compost.
  • measure the ions in plant leaves.
  • measure the amount of salts in urine and saliva.

All our EC testers listed have ATC (Auto Temperature Compensation) removing errors caused by temperature variance.
