PKY-ECpH-301 EC/pH Dosing Controller
A control module for nutrient solution dosing, EC/pH monitoring, and fertigation system integration.
Product Overview
PKY-ECpH-301 is positioned as an EC/pH control module. It is used inside fertigation and nutrient solution systems to monitor EC and pH values and control dosing equipment according to project logic.
Control module inside a fertigation or nutrient solution system.
Monitor nutrient concentration and pH values for project control logic.
Control dosing outputs according to target values and system configuration.
Connect with irrigation and fertigation system logic when required.
Typical Applications
PKY-ECpH-301 is suitable for projects that need nutrient solution monitoring and dosing control as part of a larger fertigation system.
- Hydroponics
- Greenhouse fertigation
- Vegetable production
- Small fertigation systems
- Nutrient solution control
Control Logic
The controller compares measured EC and pH values with target settings and controls dosing outputs according to the configured project logic. The final dosing method depends on pump type, tank structure, sensor position, and crop requirements.
- Target EC control
- Target pH control
- Alarm and operation status
- Integration with irrigation or fertigation timing
EC Monitoring
EC monitoring helps manage nutrient concentration in irrigation water or nutrient solution. It is commonly used for greenhouse fertigation, hydroponics, and high-value crop production.
pH Monitoring
pH monitoring helps maintain the acidity range required by the crop and nutrient formulation. pH adjustment can be connected to acid or alkali dosing equipment when the project requires it.
Dosing Pump Control
Dosing outputs can be connected to fertilizer or pH dosing pumps according to system design. The controller is not the complete fertigation machine by itself; it is the control module in the fertigation architecture.
Integration With Fertigation System
EC/pH Controller = control module. Fertigation System = complete system including water source, pump, filter, injection equipment, mixing structure, sensors, valves, and irrigation linkage.
Typical System Structure
The EC/pH controller works as one module inside a complete nutrient or fertigation system.
