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.
Bluelab Soil pH Pen measures pH and temperature in Fahrenheit and Celsius, to ensure proper nutrient uptake from nutrient solutions and soil. The completely waterproof pen features a backlit LCD, push-button readings, integrated storage cap and dibber, and automatic temperature compensation. An auto-off function and low-battery indicator ensure reliable operation. Unit carries a one-year guarantee. Battery included.
The Bluelab Soil 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.

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.
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).
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.
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 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.
