HM AP-2

This is a fully Water Proof Unit

EC Meter : EC stands for Electrical Conductivity, or the ability of a solution to conduct electricity. Electricity moves efficiently through water with high levels of salt present (high EC), and less efficiently with low levels (low EC). EC indicates how much dissolved salt is in a given sample. That is why EC is also referred to as TDS (Total Dissolved Salts) or Salinity (the amount of salts in a solution). All nutrients are salts, so EC is the same as measuring total nutrients in a solution..
