The EC value is basically the conductivity of a solution. EC is an abbreviation and stands for Electrical Conductivity.
The EC value increases as more ions (charged particles) are absorbed in a solution. These ions include various types of salts and can be residues from, for example, fertilizers (Potassium, Nitrate, etc.) or other surplus elements such as table salt or bicarbonate.
In short, the EC value tells the total concentration of the dissolved ions (salts) in a solution.
EC values are measured in Milli Siemens per centimeter or in short mS/cm, but the indication Micro Siemens per centimeter or µS/cm is also used. The difference is the ratio because 1 mS/cm equals 1000 µS/cm, but both are common terms.
The ideal EC value for you depends on your personal application. We are happy to help you measure and monitor the desired EC value accurately and reliably with one of our measuring instruments. View our range of EC meters here.
