Soil EC Tester
Model No.︰ZD-EC
Brand Name: ZD INSTRUMENT - CHINA
Application: to accurately determine the EC content in the soil. - Plants in general can live under the influence of the EC parameter, which is the electrical conductivity or EC (Electricity Conductivity) of the soil. In principle, the saltier the soil solution, the higher the ion concentration (including cations - positive ions and anions - negative ions) in the solution.
