Applications
EC [displayed in either microsiemens (μS) or micromhos (μM)] is the measurement of the nutrient solutions ability to conduct an electrical current. In hydroponics the conductivity (EC) is most commonly expressed in an equivalent Total Dissolved Solids (TDS) value. The unit of measurement for TDS is parts per million (ppm). Pure water (deionized water) is actually an insulator — it does not conduct electricity. It is the conductive substances (or ionized salts) dissolved in the water that determine how conductive the solution is. With few exceptions, when there is a greater concentration of nutrients, the electrical current will flow faster, and when there is a lower concentration, the current will flow slower.
This is because the quantity of dissolved solids in the nutrient solution is directly proportional to the conductivity. Thus, by measuring the EC, one can determine how strong or weak the concentration of the nutrient solution is.
The HortiCare Nutrient Check tester is specially designed for checking nutrient concentration used for hydroponics. The Nutrient Check is simple to use yet offers good accuracy. Nutreint concentration is one key factor to a successful hydroponics, usually refers to nutrient strength, wrong concentration not only retard growth but can also kill the plant. EC generally used by professional and commercial growers are now made available with this economical yet good quality HortiCare Nutrient Check tester.
