About this item

• For hydroponics and plants—Master your nutrient solution: No more guessing your plants, and say goodbye to plant deaths caused by inaccurate pH levels or over-fertilization. This 4-in-1 nutrient solution pen displays pH + EC + temperature simultaneously on a color backlit screen, eliminating the need to switch back and forth. Precisely determine when to add pH adjusters or dilute nutrient solutions, ensuring the pH level remains within the 5.5-6.5 range to maximize plant absorption. Includes a pH 4.0/7.0 and EC 1413μs/cm calibration kit, ready to use out of the box.
• GIDIGI 4-in-1 Water Quality Tester—Designed specifically for hydroponics. Whether using DWC, NFT, or aeroponic systems, this tester provides real-time nutrient concentration feedback, helping you precisely adjust nutrient solution ratios to ensure plants absorb nutrients at optimal ion concentrations, resulting in healthy and thriving crops such as lettuce, tomatoes, strawberries, and herbs. Measurement range: pH 0-14, EC 0-19.99 mS/cm, TDS 0-9999 ppm, temperature 0.0-140.0°F. Built-in automatic temperature compensation ensures stable and reliable readings, making it an ideal choice for hydroponics beginners and experienced growers.
• For drinking water and reverse osmosis systems—Understand your drinking water: Quickly test your tap water, reverse osmosis system, or water purifier. This 4-in-1 TDS pH meter displays pH + TDS + temperature simultaneously on a large digital screen, eliminating the need to switch between functions. The ideal pH for drinking water should be between 6.5 and 8.5, and the TDS should be below 500 ppm. Its portable design makes it easy to test various outdoor water qualities. Four AAA batteries extend its usage time, and the side-backlit screen ensures clear visibility even in dimly lit areas under the sink.
• Easy-to-use pH meter with ATC and pH reset function—Eliminates tedious operation steps; simply insert the probe into the water to read pH, TDS, EC, and temperature. This pH meter features a high-sensitivity probe with a resolution of 0.1, and the replaceable probe design extends the device's lifespan. Additional probes are available at GIDIGI stores. If you encounter calibration errors, simply reset the pH to the correct point.
• More features of the GIDIGI pH meter—The kit includes the meter, 8 AAA batteries, calibration accessories, and a user manual. Ideal for hydroponics, aquariums, drinking water, swimming pools, plant care, and home brewing. Built-in pH reset function (press and hold the power button for 5 seconds) and automatic temperature compensation for quick testing of various water qualities. Three parameters are displayed simultaneously without switching modes. The lightweight pen-style design makes it easy to carry to the garden, greenhouse, or poolside.
