Essentials EC Meter

Essentials EC Meter How to Measure EC / CF: The conductivity of a solution is an expression of the capacity of that solution to conduct an electric current. As nutrient salts are dissolved in the water so the conductivity of the solution increases. The conductivity of a nutrient solution is therefore a measurement of its strength as indicated by the actual amount of salts dissolved. Conductivity is usually expressed in terms of CF or EC. CF stands for Conductivity Factor, EC stands for Electrical Conductivity. The difference between these is purely in the placing of the decimal point. An EC unit is equal to 10 CF units so an EC of 1.2 would be a CF of 12. The most accurate way to check EC/CF levels is to use the Essentials professional EC digital meter or Trident tri-meter. You simply dip the electrode into the nutrient solution for a few moments and the EC value is displayed on an LCD display. Essentials EC meters are very accurate and fast. However like all laboratory graded instruments, it needs to be cared for properly. Make sure you calibrate your EC/CF meters regularly with Essentials CF Standard.
