PH Meters, TDS / PPM / EC Meters & Calibration

PH meters allow you to monitor the PH of your water or grow medium to ensure proper nutrient uptake. TDS (total dissolved solids) meters monitor PPM (Parts Per Million) or EC (Electrical Conductivity), this allows you to measure the amount of nutrients in your water when you are mixing your feeding solution.
