Nutrient regulator designed to keep the concentration of the nutrient solution used in hydroponics and irrigation water monitored. The HI981413 uses an amperometric conductivity sensor to measure the amount of fertilizer in the solution. The instrument can be programmed to display results as EC (electrical conductivity) or as TDS (total dissolved solids). EC results are displayed as mS / cm while TDS is displayed as ppm with a selectable conversion factor from 0.45 to 0.99. HI981413 was developed as an economical solution for hydroponic systems to maintain ideal concentration levels of fertilizers in nutrient solutions.
