The Hygen pH Test Kit – Up/Down & Indicator measures pH levels in hydroponic nutrient solutions, irrigation water, and pH adjustment products. It features specialized colorimetric reagents that provide clear visual indications for standard pH testing, as well as verification of pH up and pH down solution concentrations. A included color chart allows readings from pH 4.0 to 9.0 with dropper-based application for quick results. Accurate pH control optimizes nutrient solubility and plant uptake, reducing risks of lockout, deficiencies, or toxicities. Suitable for soil, hydroponic, and soilless systems in additive and nutrient management.
