Conductivity 2.76 Calibration Solution

To ensure accurate readings, it is essential to calibrate your ElectricalConductivity (EC) or TDS (Total Dissolved Solids) meter with QualityScientific Grade HY-GEN Conductivity Calibration Solution regularly

.The Electrical Conductivity (EC), measured as millisiemens (mS/cm2),Conductivity Factor (cF) or parts per million (ppm) is the measurement ofavailable nutrient in the solution. The conductivity increases as nutrientincreases. Distilled or deionised water will give a near zero reading.

As ageneral guide for hydroponics: 1mS/cm2= 10cF = 700ppm.Nutrient requirements vary from plant to plant; therefore the ideal conductivity varies from plant to plant.
