GIDIGI pH Meter 4 in 1 For Hydroponic Water Digital pH and TDS EC Tester With Easy Calibration

Test hydroponic solutions with confidence with GIDIGI's 4-in-1 pH tester. Designed for home growers, this compact device measures real-time pH, EC, TDS and water temperature so you know exactly when to adjust nutrients for optimal growth of your houseplants, DWC or other hydroponic applications.

• 4 in 1: pH, EC, TDS and temperature: complete measurements in one instrument, for a holistic monitoring of the nutrient solution.
• Dual display with green illumination: pH and ppm values are displayed simultaneously on a clear, backlit display for quick reading in low-light environments.
• Extended measurement range: pH 0–14; EC 0–9990 μS/cm (10.01–19.99 mS/cm); TDS 0–9990 ppm; temperature 0.0–60.0 °C (32.0–140.0 °F).
• Automatic Temperature Compensation (ATC): provides consistent readings between 0°C and 50°C, reducing variations caused by water temperature.
• pH sensor with 0.1 resolution: sensitive probe for accurate readings; sponge cover included to keep electrode moist and extend life.
• Easy calibration with buffer solutions: the package includes buffer solutions pH 4.00, 7.00 and 10.01 (50 ml each) for quick and safe calibration of the device.
• Portable and ergonomic: Pen-type design, easy to maneuver in tight spaces and ideal for use in your household or cottages.

This tester is the right tool for anyone monitoring plant health by keeping pH values ​​in the optimum range for hydroponics. Nutrient agents, quick responses to environmental changes and simplified calibration make it a reliable ally for both hobby and professional use in small farms. Whether you're building your solution for houseplants, an aquarium, or a DWC hydroponic system, this 4-in-1 gives you the insight you need for consistent, healthy growth.
