Bluelab pH Controller Wi-Fi

Bluelab pH Controller Wi-Fi — Automate pH control in your nutrient reservoir

A drifting pH means repeated checks and manual corrections. The Bluelab pH Controller Wi-Fi takes care of this routine in your hydroponic reservoir: it continuously measures pH and doses adjuster towards your chosen target. Set the controller locally or manage it remotely with Edenic, while reducing the need for hands-on adjustments to your nutrient solution.

Practical benefits for hydroponic growing

• Ongoing control: the controller responds when pH moves away from your target, without waiting for your next handheld measurement.
• Fewer manual adjustments: the integrated pump delivers adjuster according to your dosing settings, leaving more time for inspecting plants and maintaining the system.
• Remote visibility: Edenic gives you access to readings, history, alerts and settings from your phone.
• Dosing suited to your reservoir: adjust pump speed, injection duration and mixing pauses to match water volume and circulation.
• Temperature-compensated measurements: the separate temperature probe lets the controller compensate pH readings for solution temperature.

An integrated pump for your chosen correction direction

The controller combines a peristaltic pump with a replaceable pH probe. Choose to lower pH with pH Down or raise it with pH Up. One correction direction is used at a time. Pauses between injections allow the adjuster to mix through the reservoir before the next measurement.

High and low alarms stop dosing when the configured thresholds are exceeded. These safeguards complement your dosing settings; good circulation and supervision of the first cycles remain essential. Automatic temperature compensation supports reliable pH measurement.

Wi-Fi and Edenic: stay connected to your reservoir

Built-in Wi-Fi links the controller directly to Edenic. Add the device in the app and connect it to your network to access readings and settings remotely. Position the controller where Wi-Fi coverage is strong enough for connected functions. Local pH control remains available with Wi-Fi disabled.

Installation and initial settings

1. Mount the controller near your reservoir and connect the power supply and both probes. Their 2 m cables provide flexibility for positioning.
2. Calibrate the pH probe before first use with suitable calibration solutions, then place both probes in the nutrient solution, away from the dosing point.
3. Connect the dosing tube between the adjuster container and the reservoir. Keep its outlet above the maximum solution level.
4. Choose your pH target and correction direction, then set pump speed, dosing duration, mixing interval and alarm limits.
5. Observe the first dosing cycles before leaving the controller to regulate. Add the device to Edenic if you want remote access.

Key specifications and included equipment

• pH measurement range: 0.0–14.0; specified accuracy ±0.1 pH at 25 °C.
• Temperature measurement: 0–50 °C, with °C or °F display.
• Variable-speed pump: up to 120 ml/min.
• Reservoirs up to 7,600 litres according to Bluelab; dosing cycles must suit the installation.
• Includes the controller, pH and temperature probes, power supply, 4 m dosing tube and calibration solution sachets.

Probe care for dependable measurements

Clean and calibrate the pH probe regularly. Bluelab recommends monthly maintenance and calibration after cleaning. Keep the probe tip hydrated with KCl storage solution when it is not in use, and check the pump tubing and connections. Reliable readings and a well-maintained dosing circuit are essential for effective regulation.

The GrowLED tip: start with short doses and allow enough mixing time. Adjuster released too close to a probe can produce a misleading local reading. Place the probes in a well-mixed area away from the injection point, then refine settings by observing how the whole reservoir responds.
