Bluelab PH Controller

The Bluelab Automatic pH Controller delivers hands-free, 24/7 reservoir management, automatically monitoring and adjusting pH levels to maintain optimal nutrient availability. Fluctuations in water chemistry are common in active hydroponic systems as plants consume nutrients and water. When pH drifts out of range, crops experience nutrient lockout, leading to leaf yellowing, weak stem structure, and stunted growth. This commercial-grade 14-piece controller kit automates dosing routines, keeping your nutrient solution locked within a tight 0.05 pH tolerance of your set target.

Equipped with a built-in peristaltic dosing pump, the controller injects precise volumes of pH Up or pH Down adjusters directly into the tank at a controlled rate of 10 ml per minute. To prevent over-dosing, the unit features a programmable "On/Off" dosing timer cycle. The "Off" delay allows added adjusters to fully mix and equalise throughout the reservoir before the probe takes a new reading, eliminating drastic pH swings caused by premature secondary dosing.

Featuring a clear, backlit LCD screen with multi-language support, the controller displays real-time pH and solution temperature. Integrated high and low visual alarms flash on screen if parameters move outside safe bounds, providing immediate warning in busy grow environments. Suitable for reservoirs up to 760 litres, the unit includes international power adapters, a double-junction pH probe, a temperature probe, dosing tubing, and single-use calibration packets for fast setup.

Key Benefits:

• Automated 24/7 pH Regulation: Keeps nutrient solution locked within 0.05 pH of target levels without manual testing or hand-dosing.

• Overdose Lockout Protection: Programmable "On" and "Off" dosing intervals give adjusters time to fully mix into the solution before re-testing.

• Precision Peristaltic Pump: Integrated pump delivers controlled 10 ml/min dosing directly from stock adjuster bottles.

• Flashing High/Low Alarms: Visual warning display flashes on screen if reservoir parameters drift out of safe set ranges.

• Double-Junction Probe Security: Includes a robust Bluelab double-junction pH probe that resists chemical fouling from heavy mineral salts.

• Global Compatibility: Packed with four interchangeable power adapters (UK, EU, US, AU/NZ) and multi-language software settings.
