pH & EC controller for hydroponic：To better understand the evolution of hydroponic crops. So the hydroponic system needs to be monitored, Our automating measuring instruments are not only having sensors that can take readings at predefined intervals but also making sure that the reading from these sensors are stored so that they can be used for analysis and diagnosis later on. It provides reliable dosing when required to maintain a constant pH and ec level in a hydroponic system. It is on the job 24 hours a day, 7 days a week and an alarm function and relay keep the requirement value.
