Bluelab pH Controller Wi-Fi – Automatic pH Dosing Controller for Hydroponics

The Bluelab pH Controller Wi-Fi is an automatic pH monitoring and dosing system designed to maintain consistent pH levels in hydroponic nutrient reservoirs. Equipped with an integrated peristaltic dosing pump, it measures solution pH and temperature continuously and dispenses corrective solution when adjustments are required.

Built-in Wi-Fi connectivity allows growers to monitor reservoir conditions, receive notifications, and access supported settings remotely through the Edenic by Bluelab app.

With programmable dosing intervals, adjustable pump speed, and built-in safety features, this controller helps reduce manual pH adjustments while supporting more consistent nutrient management.

The Bluelab pH Controller Wi-Fi is suitable for hydroponic systems, indoor cultivation facilities, commercial greenhouses, and automated nutrient reservoirs.

Automatic pH Adjustment and Dosing Control

Maintaining the correct pH range helps plants absorb nutrients efficiently. However, nutrient uptake, water quality, and changes in reservoir chemistry can cause pH levels to fluctuate.

The Bluelab pH Controller Wi-Fi uses dedicated pH and temperature probes to monitor the reservoir and regulate pH according to a programmed target.

Its integrated variable-speed peristaltic pump delivers either pH Up or pH Down, depending on the selected operating mode, at a maximum flow rate of 120 mL/min.

Programmable dosing and mixing intervals allow the solution to circulate between adjustments, reducing the risk of overcorrection. The system is designed to maintain pH within approximately 0.1 of the selected target, under suitable operating conditions.

High and low pH alarms, programmable safety lockouts, and automatic dosing recovery after a power interruption provide additional operational protection.

Wi-Fi Connectivity and Edenic App

The controller connects to the Edenic by Bluelab app through Wi-Fi, allowing growers to access important reservoir information from a compatible device.

The app supports:

• Remote monitoring of pH and nutrient solution temperature.
• Notifications when measurements exceed configured limits.
• Access to historical readings and reservoir trends.
• Remote adjustment of supported controller settings.
• Organized monitoring of reservoir conditions over time.

Wi-Fi connectivity can be enabled or disabled according to the needs of the installation.

Key Features and Benefits

• Integrated dosing pump: Automatically dispenses pH-adjusting solution without requiring a separate pump.

• Adjustable pump speed: Provides dosing control with a maximum capacity of 120 mL/min.

• Continuous monitoring: Tracks pH and temperature using dedicated probes.

• Automatic temperature compensation: Supports consistent pH measurements as reservoir temperature changes.

• Wi-Fi connectivity: Provides access to compatible Edenic monitoring and control features.

• Programmable dosing intervals: Allows mixing time between corrective additions.

• Alarm and safety functions: Help detect abnormal pH conditions and prevent excessive dosing.

• Replaceable probes: Simplify maintenance and long-term operation.

• Wall-mounted design: Suitable for permanent installation near nutrient reservoirs.

Installation and Setup

Proper installation and calibration are essential for accurate and safe automatic pH control.

Step 1 – Mount the Controller

Install the controller near the nutrient reservoir, allowing sufficient space for the probes, dosing tubing, and electrical connections.

Step 2 – Position the Probes

Connect the supplied pH and temperature probes and place them in an area with adequate solution circulation.

Step 3 – Install the Dosing Tubing

Connect the supplied PTFE tubing to the peristaltic pump. Position the intake tube in the appropriate pH-adjusting solution and the discharge tube in a well-circulated area of the reservoir.

Step 4 – Calibrate and Configure

Calibrate the pH probe using fresh pH 7.0 and pH 4.0 solutions. Set the target pH, select the correction direction, and configure the pump speed and dosing intervals.

Step 5 – Activate Automatic Control

Verify the readings and dosing configuration before enabling automatic operation.

Step 6 – Connect to Edenic

Follow the instructions in the Edenic app to connect the controller through Wi-Fi and enable supported remote features.

Important: Use only compatible pH-adjusting solutions and follow Bluelab's chemical concentration limits, installation procedures, and safety instructions.

Maintenance and Safe Operation

Regular maintenance helps ensure accurate measurements and reliable dosing performance.

Clean and calibrate the pH probe according to Bluelab's recommendations, using fresh calibration solutions. Inspect the pump tubing and connections regularly for wear, leaks, or chemical deterioration.

Use only pH-adjusting solutions that meet the manufacturer's chemical compatibility and concentration limits. Ensure adequate reservoir circulation so corrective solutions mix properly before additional dosing occurs.

Periodically verify the controller's readings with an independent calibrated pH meter, particularly when managing large nutrient reservoirs or commercial growing systems.

Frequently Asked Questions

Does the Bluelab pH Controller Wi-Fi measure EC?

No. This model measures pH and temperature only. For EC monitoring and automated nutrient dosing, the Bluelab Pro Controller Wi-Fi is a more suitable option when paired with compatible PeriPod equipment.

Can the controller dispense pH Up and pH Down simultaneously?

No. It operates in one selected correction direction at a time. Growers must configure the system for either pH Up or pH Down.

Are pH-adjusting solutions included?

No. The controller includes the dosing pump, probes, tubing, and listed installation accessories, but pH-adjusting solutions must be purchased separately.

Does the controller require an internet connection for automatic dosing?

Wi-Fi is used for Edenic connectivity and remote functions. Once properly configured, the controller can perform its local pH monitoring and dosing functions without an active internet connection.

What happens after a power interruption?

The controller supports automatic dosing recovery following a power interruption. Growers should verify the measurements, settings, and reservoir conditions after power is restored.

Is the Bluelab pH Controller Wi-Fi suitable for commercial hydroponic systems?

Yes. It can be used in commercial greenhouses and hydroponic installations that require continuous pH monitoring and automated correction, provided the dosing capacity and operating requirements suit the reservoir.
