{"product_id":"bluelab-ph-controller","title":"Bluelab PH Controller","description":"\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eEquipped 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.\u003c\/p\u003e\n\u003cp\u003eFeaturing 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.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey Benefits:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eAutomated 24\/7 pH Regulation:\u003c\/b\u003e Keeps nutrient solution locked within 0.05 pH of target levels without manual testing or hand-dosing.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eOverdose Lockout Protection:\u003c\/b\u003e Programmable \"On\" and \"Off\" dosing intervals give adjusters time to fully mix into the solution before re-testing.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePrecision Peristaltic Pump:\u003c\/b\u003e Integrated pump delivers controlled 10 ml\/min dosing directly from stock adjuster bottles.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eFlashing High\/Low Alarms:\u003c\/b\u003e Visual warning display flashes on screen if reservoir parameters drift out of safe set ranges.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eDouble-Junction Probe Security:\u003c\/b\u003e Includes a robust Bluelab double-junction pH probe that resists chemical fouling from heavy mineral salts.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eGlobal Compatibility:\u003c\/b\u003e Packed with four interchangeable power adapters (UK, EU, US, AU\/NZ) and multi-language software settings.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eProduct Specifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eBrand:\u003c\/b\u003e Bluelab\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eTarget Capacity:\u003c\/b\u003e Hydroponic Reservoirs Up to 760 Litres\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eControl Range:\u003c\/b\u003e 0.1 – 13.9 pH\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eDosing Rate:\u003c\/b\u003e 10 ml \/ minute\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePower Supply:\u003c\/b\u003e 100–240 Vac \/ 50–60 Hz (24V DC 0.4A Output)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eDimensions:\u003c\/b\u003e 20 cm × 11 cm × 21 cm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eCertifications:\u003c\/b\u003e CE \u0026amp; FCC Certified\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bluelab","offers":[{"title":"Default Title","offer_id":58075556774219,"sku":"HYD-2519","price":499.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/8101\/6651\/files\/bluelab-ph-controller-2264224.jpg?v=1788154135","url":"https:\/\/florifi.co.uk\/products\/bluelab-ph-controller","provider":"Florifi","version":"1.0","type":"link"}
