E-Mode’s pH + EC Controller Set (No Wi‑Fi) bundles two standalone dosing controllers for hydroponic reservoirs: the EC Lite and pH Lite. Together they automate nutrient strength and acidity using dedicated electrodes and onboard peristaltic pumps. The EC controller regulates concentration from 0.1–5.0 mS and supports three-component dosing; the pH controller maintains a user-set range (PID-regulated; 5.5–6.5 default) within a 3.0–14.0 measurement span. Both units suit systems from 10 to 2000 liters. Typical pump rates are 47 ml/min (EC) and 60 ml/min (pH). Each includes the respective probe, calibration solutions, tubing, and wall mounts. Power 220–240 V, 50 Hz; IP64 housings. This set is offline (no Wi‑Fi) and intended for direct, local control of nutrient solution parameters.
