The Bluelab pH Pen accurately measures both the pH and temperature in hydroponic systems. It's fully waterproof and also features a backlit LCD with the option to display in Celsius and Fahrenheit, double-junction probe, successful calibration indicator, hold function, low-battery warning, auto-off function and automatic temperature compensation. This pH pen has a range of 0.0 to 14.0 pH, with an accuracy of ± 0.1 pH, and 0 C to 50 C or 32 F to 122 F. It requires one AAA battery and has a one-year warranty. Battery included.
The Bluelab ppm Pen measures conductivity and temperature and ensures plants are receiving the proper amounts of nutrients. It's fully waterproof and also features a backlit LCD display, optional calibration and a successful calibration indicator, hold function, low-battery warning, auto-off function and automatic temperature compensation. It operates on a scale of 500 or 700ppm and has a range of 0 to 5,000 ppm or 0 to 7,000 ppm, with an accuracy of ± 50 ppm or ± 70 ppm. Requires one AAA battery and has a one-year warranty. Battery included.
The Bluelab pH Controller automatically monitors and controls pH within reservoirs up to 200 gallons (760 liters). The flashing high/low alarm with control lockouts includes dosing lockouts to protect from over-dosing, and auto-resume dosing on restart after power loss to ensure fine-tuned pH levels. The plant-safe green backlit LCD with adjustable brightness features a large, easy-to-read display, with easy-to-navigate menus. The water-resistant and wall-mountable controller also includes a 13-foot acid/alkali-resistant dosing tube. For best results use with undiluted Bluelab pH Up or Down.
The Bluelab Guardian is a constant indicator of the desired levels of EC, pH and temperature, allowing these parameters to be optimized as the crop progresses through each growing phase. A flashing display indicates if a parameter moves away from the desired level, allowing gardeners to make the required adjustments quickly. The Guardian monitors crops 24 hours a day with a built-in alarm system, and also features large, easy-to-read displays with adjustable plant-safe green LED lights, adjustable conductivity and temperature values, push button pH calibration, a silent alarm for both high and low settings, setting retention even during power failure, automatic temperature compensation, and a water-resistant design. The meter ranges are pH from 0.0 to 14.0 with a 0.1 resolution, EC from 0.00 to 5.00 with 0.1 resolution, and temperature from 32 F to122 F (0 C to 50 C) with a 1-degree resolution. The accuracy is ± 0.1 for pH and EC, ± 2 F (± 1 C) for temperature. This product is protected by two-year warranty.
Easily measure and maintain nutrient strength levels with the waterproof Bluelab Truncheon® Nutrient Meter. This meter reads in EC (0.2 to 3.6), CF (2 to 36), TDS/ppm 500 (100 to 1,800) and ppm 700 (140 to 2,520). Accurate within ± 4 percent of reading with a resolution of 0.1 EC, the Truncheon runs on three AA alkaline batteries and comes with a five-year guarantee. Batteries included.
The Bluelab Grower’s Toolbox combines the essential tools to easily manage crops by measuring the pH, conductivity (ppm) and temperature of the nutrient solution. Learn basic hydroponics with The Grow Book. Keep growing with the ultimate handy team, the Bluelab pH Pen and Bluelab ppm Pen. The included Bluelab Probe Care Kit makes maintenance easy and maximizes the life and accuracy of the pens’ probes.
Bluelab pH Probe KCl Storage Solution is made specifically for use with Bluelab pH products. It is designed to increase response time and maximize the life of Bluelab pH pens and pH probes. For best results, KCl storage solution should be used to store the pH pen/probe after use. Bluelab pH Probe KCl Storage Solution is manufactured to high laboratory standards.
The Bluelab pH Meter is a simple, reliable pH meter that provides accurate readings and unparalleled ease of use. Growers can use this AAA-battery-powered portable meter anytime, anywhere with its simple push-button pH calibration. Its auto-off function extends battery life, and its large display makes it a breeze to read. This meter includes a double-junction pH probe, pH calibration solutions, two AAA batteries and a five-year guarantee on the meter, six months on the probe. Replacement probe BCM505 is compatible with this meter.
Use Bluelab pH Up and Down to adjust nutrient solutions to the optimum range of pH and improve nutrient availability to plants. Bluelab's pH Down is made of 35 percent w/w phosphoric acid, and pH Up is made of 35 percent w/w potassium hydroxide. The premium-quality acid concentrations are easy to use in any growing system. Use undiluted with Bluelab pH Controllers and Bluelab pH Controller Connect.
