pH, EC, TDS, salinity and temperature cover the core readings commonly monitored in a home hydroponic reservoir, in one pen instead of a pH meter and a TDS meter side by side.

Home hydroponic reservoirs and nutrient solution checks.
Uneven nutrient film flow or oxygen imbalance is one of the biggest frustrations in NFT and DWC hydroponic systems. This tester solves it by monitoring pH and EC in real time, so you can adjust before plants suffer. Basil, mint, and other herbs thrive best at pH 5.5–6.5 and EC 1.0–1.6 mS/cm, and this device ensures your nutrient solution stays in that sweet spot. That means stronger roots, faster growth, and fewer wasted crops.
Stop worrying about inaccurate nutrient readings—this tester’s sensitive electrodes and stable sensors ensure reliable water analysis every time. With its long-life coin cell batteries, you get uninterrupted monitoring of your hydroponic system, even during intensive growing cycles. For leafy greens like lettuce, keeping pH between 5.8–6.2 and EC at 0.8–1.2 mS/cm is crucial for crisp, fast growth, and this device helps you maintain those perfect numbers without guesswork.
From hydroponic nutrient tanks to drinking water and aquaculture, this all-in-one tester helps you maintain clean, balanced water quality across multiple uses. Say goodbye to juggling different meters—this compact solution fits every environment. By checking your water in pools, fish tanks, and plants with one tool, you save time and keep every system in balance.

Experts recommend measuring pH and EC about 2–3 times per week—and even daily during peak growth phases—to maintain nutrient balance and prevent harmful fluctuations.
Most plants thrive with a pH between 5.5–6.5, while DWC systems are especially sensitive to extremes. The water tester 0-14.0 pH range and accurate electrodes help growers stay in this ideal window, reducing nutrient lockout and energizing growth.
EC indicates nutrient concentration, and TDS reflects dissolved solids—both essential for diagnosing over- or under-feeding.
And the device covers both, providing real-time insights so growers can fine-tune nutrient strength for healthier development.
Yes—water temperature should stay between 18–24 °C (65–75 °F). Above 28 °C, oxygen levels drop; below 15 °C, root activity slows
Absolutely. Monitoring pH, EC, TDS, and temperature together helps you catch nutrient imbalances before they harm roots. High EC from evaporation, for example, can be spotted and corrected immediately.
Definitely. Instead of separate meters for each parameter, your 5-in-1 tool consolidates functionality into one compact device. Growers save time, reduce calibration complexity, and minimize error—since everything is measured with one set of electrodes and a single interface
