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 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.
The Bluelab Meter Carry Case allows readings without removing the meter from its protective case. An adjustable nylon strap can be used to hang the case and meter on the wall or over a shoulder so only the probe goes near the nutrient solution. The case’s firm shell with zipper closure protects the meter against accidental impact, and the net pocket and straps inside keep the meter and probes securely in place.
The instrument is only as accurate as the probe is clean. Probe cleaning is one of the most important parts of owning or operating any Bluelab meter, monitor or controller. The probe surface is where the instrument takes the reading of the solution or soil/media. If the probe face is dirty or contaminated, then the reading will be inaccurate. Accurate readings simplify crop management and provide improved growth.
The Bluelab pH Controller Connect gives gardeners clever monitoring, dosing and data logging of solution pH levels. By wirelessly data logging to a computer, continuous information is always available. Use the data to make system changes faster. The pH Controller Connect also allows for changes to settings from a personal computer and has local and Cloud data logging capability (download free Bluelab Connect Software). With the pH Controller Connect, automatically monitor and control pH within reservoirs up to 200 gallons (760 liters). The flashing high/low alarm with control lockouts, including dosing lockouts to protect from over-dosing, and auto resume dosing on restart after power loss ensures fine-tuned pH levels. The plant-safe green back lit 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 pH Controller Connect is compatible with Bluelab Connect Stick and Bluelab Connect Range Extender.
Probe cleaning is one of the most important parts of owning or operating any Bluelab meter, monitor or controller. The probe surface is where the instrument takes the reading of the solution or growing media and needs to be properly maintained for reading accuracy. Accurate readings simplify crop management and provide improved growth. The Bluelab Probe Care Kit, pH includes Probe care instructions, 20-milliliter single use Bluelab Solution Sachets, two each of: pH7.0 and pH 4.0 KCI, three plastic cups, Bluelab pH Probe Cleaner, Bluelab Toothbrush (pH probe cleaning instrument).
