Bluelab Pro Controller

Bluelab Pro Controller — Automated pH, EC & Temperature Management for Commercial Hydroponic Reservoirs

The Bluelab® Pro Controller™ is the central automation hub for professional hydroponic and controlled-environment agriculture (CEA) operations that demand precise, continuous control of reservoir pH, electrical conductivity (EC), and temperature. Designed to eliminate manual dosing and guesswork, the Pro Controller continuously monitors all three parameters and automatically triggers the Bluelab® PeriPod™ dosing system to maintain optimal growing conditions around the clock — without operator intervention.

The Pro Controller’s plant-safe green backlit LCD with adjustable brightness provides a clear, at-a-glance view of current reservoir conditions. An easy-to-navigate menu allows growers to program target set points, adjust alarm thresholds, and calibrate probes with a simple push of a button. Flashing high/low alarms with control lockouts protect against over-dosing, and auto-resume dosing on restart after power loss ensures continuity in critical growing environments. The system includes a water-resistant, wall-mount housing, 13 ft of acid/alkali-resistant dosing tube, an international power supply, a replaceable double-junction pH probe, and a temperature probe for pH automatic temperature compensation (ATC).

For temperature control, pair the Pro Controller with the Bluelab® PowerPod™ to activate mains-powered heaters and coolers. For remote monitoring and data logging, connect to the Bluelab Connect ecosystem via the Bluelab Connect Stick. For reservoirs located more than 6.5 ft from the controller, add the Bluelab Sample Pot for accurate probe placement. Use with undiluted Bluelab pH Up or Down only.

Frequently Asked Questions

What does the Bluelab Pro Controller do and how does it work?

The Bluelab Pro Controller is an automated reservoir management system that continuously monitors pH, EC, and temperature in your hydroponic nutrient solution. When any parameter drifts outside your programmed target range, the controller sends a dosing trigger to the connected Bluelab PeriPod dosing system, which then delivers the appropriate pH adjuster or nutrient stock solution to bring the parameter back into range. This closed-loop process runs automatically 24 hours a day, maintaining stable reservoir conditions without manual intervention. The result is more consistent growing conditions, reduced labor, and improved crop performance.

What accessories do I need to complete a Bluelab Pro Controller system?

The core automated dosing system requires the Bluelab Pro Controller paired with a Bluelab PeriPod dosing unit (M3 or M4, depending on the number of dosing channels needed). For temperature control, add the Bluelab PowerPod to activate mains-powered heaters and coolers. For remote monitoring and data logging, add the Bluelab Connect Stick and compatible Connect devices. For reservoirs located more than 6.5 ft from the controller, add the Bluelab Sample Pot. The Bluelab Alarm Box can also be added for enhanced alerting. All accessories are available from Seres Ag.

How do I calibrate the Bluelab Pro Controller?

pH calibration is performed directly on the Pro Controller using the simple push-button menu with Bluelab pH 7.0 and pH 4.0 calibration solutions. EC and temperature are factory-calibrated and require no field calibration. Bluelab recommends calibrating the pH probe at least once a week in active growing environments. The replaceable double-junction pH probe carries a 6-month guarantee and can be replaced without replacing the controller unit.

What happens to the Bluelab Pro Controller if power is lost?

The Bluelab Pro Controller features auto-resume dosing on restart after power loss. When power is restored, the controller automatically resumes monitoring and dosing without requiring manual reprogramming. All programmed set points and alarm thresholds are retained in non-volatile memory, ensuring continuity of reservoir management even after unexpected power interruptions.

Where can I buy the Bluelab Pro Controller?
