Calibration solutionEC 1,413mS/cm

Electroconductivity solution EC 1.413 mS/cm for the calibration of conductivity meters.

EC measuring instruments must be calibrated regularly and fertilizer solutions checked frequently.

The degree of electro conductivity of hydroponic solutions will have a direct impact on the morphology of your plants, their quality and the abundance of the harvest.
