Growth Tech EC Standard 1.4ms
Solutions of a known electrical conductivity (EC) used to check and calibrate EC meters. This should be a regular procedure to ensure best results from the meter.
The two most important factors in nutrient and water management are conductivity and pH, and a good understanding of these variables is essential for successful hydroponic gardening.
The conductivity of a solution is an expression of the capacity of that solution to conduct an electric current. Distilled or de-ionised water will conduct virtually no electricity at all and therefore will have a conductivity reading of zero. As 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.
