pH + EC Controller Set Wi‑Fi by E‑Mode combines two Wi‑Fi‑enabled dosing controllers for hydroponic nutrient management. The pH controller continuously measures solution pH and automatically doses pH+ or pH− via two built‑in peristaltic pumps when readings move outside a user‑defined range. The EC controller measures conductivity and water temperature (NTC thermocompensation) and doses up to three nutrient components (A/B/C) with adaptive control, including a PI‑based algorithm, dosing pauses, and safety interlocks. Both devices connect to E‑Mode’s cloud for remote setup, 24/7 monitoring, history, and email alerts. The set is suitable for closed‑loop hydroponic systems and supports fully automatic or manual dosing modes for calibration and service. Typical use covers reservoirs from 20 to 2000 liters, with components A/B/C proportions and tank size configured in software.
