Bluelab pH Controller - Connect

Bluelab pH Controller Connect — Automated pH Monitoring, Dosing & Wireless Data Logging

The Bluelab® pH Controller Connect is a fully automated pH management system that continuously monitors and adjusts the pH of your hydroponic reservoir — and wirelessly data-logs every reading to your computer in real time. Designed for growers who want hands-free pH control with complete data visibility, the pH Controller Connect combines automated dosing with local and cloud-based data logging, giving you the information you need to make faster, smarter crop decisions.

The controller constantly measures reservoir pH and automatically doses Bluelab pH Up or Down (undiluted) to maintain your target range. Wireless connectivity via the Bluelab Connect Stick (sold separately) enables continuous data logging to your computer through the free Bluelab Connect Software, with the option to view data and current status remotely via Google Docs™. Settings can also be adjusted remotely from your PC. Suitable for reservoirs up to 200 US gal / 760 L.

Built for reliability and ease of use, the unit features a plant-safe green backlit LCD with adjustable brightness, a large easy-to-read display, a simple push-button menu for programming and calibration, flashing high/low alarms with control lockouts to prevent over-dosing, and auto-resume dosing after power loss. The water-resistant, wall-mount housing is designed for grow room environments. Includes 13 ft of acid/alkali-resistant dosing tube, international power supply, replaceable double-junction pH probe, and temperature probe for automatic temperature compensation (ATC). The pH probe carries a 6-month guarantee.

Frequently Asked Questions

What does the Bluelab pH Controller Connect do and how does it work?

The Bluelab pH Controller Connect continuously measures the pH of your hydroponic reservoir and automatically doses Bluelab pH Up or Down to maintain your target pH range. When the controller detects that pH has drifted outside your set parameters, it activates the dosing pump to deliver the appropriate pH adjuster through the included acid/alkali-resistant tubing. Simultaneously, it logs all pH and temperature readings wirelessly to your computer via the Bluelab Connect Stick, building a complete historical record of your reservoir conditions.

Does the Bluelab pH Controller Connect require the Bluelab Connect Stick?

The Bluelab Connect Stick is required for wireless data logging and remote monitoring functionality. Without the Connect Stick, the pH Controller Connect will still operate as a fully functional automated pH controller — monitoring and dosing pH automatically — but wireless data logging and remote access via Bluelab Connect Software or Google Docs™ will not be available. The Connect Stick is sold separately and is compatible with the Bluelab Connect Range Extender for extended wireless range.

What size reservoir is the Bluelab pH Controller Connect suitable for?

The Bluelab pH Controller Connect is designed for reservoirs up to 200 US gallons (760 liters). For larger commercial reservoirs, the Bluelab Pro Controller paired with a PeriPod dosing system offers greater capacity and multi-parameter control (pH, EC, and temperature). For smaller hobby or mid-size grows, the pH Controller Connect is an excellent standalone automated pH solution.

How do I calibrate the Bluelab pH Controller Connect?

Calibration is performed directly on the unit via the easy-to-navigate push-button menu, with on-screen instructions guiding you through the process. Standard two-point calibration uses pH 7.0 (buffer) and pH 4.0 (slope) reference solutions. Bluelab recommends calibrating the pH probe at least once a week in active growing environments to maintain measurement accuracy. The replaceable double-junction pH probe is designed for easy swap-out when the probe reaches the end of its service life.
