Product Details
✓24/7 Continuous Monitoring, No More Test Pens : Stop wasting time with unstable handheld test pens. This 4-in-1 monitor provides continuous, round-the-clock tracking of pH, EC, TDS, PPM, and water temperature. It works as the ultimate digital brain for your indoor hydroponic grow system, grow tent, DWC reservoir, or aquaponics setup, ensuring your plants never miss an optimal growth window.
✓Check Water Quality Remotely via Smart App : No need to constantly unzip your grow tent or disturb your home garden environment. Connect via 2.4GHz WiFi to track live water conditions anytime, anywhere. Receive instant push notifications on your smartphone the moment your nutrient solution values drift out of your customized range, allowing for proactive, hassle-free balance.
✓Seamless Auto-Sync Display & Easy Setup : Enjoy a clutter-free grow space. The high-precision submerged green probe and the gray local display connect completely wirelessly, supporting a reliable transmission range of up to 16.4 feet (5m). Once both units are powered on, they pair automatically in seconds, and the onscreen warning icon (!) clears instantly to confirm a stable local link.
✓Historical Trend Graphs & App Data Export : Take the guesswork out of scientific indoor cultivation. The smart App automatically records all water parameter history over time. Easily track nutrient spikes or pH shifts on interactive graphs directly inside the App, or export full data files via CSV to your computer for deep technical analysis of crops like lettuce, tomatoes, or herbs.
✓High Precision Under Varying Temperatures : Indoor lights and environments cause constant water temperature fluctuations, which ruin normal tester readings. Engineered with Automatic Temperature Compensation (ATC) from 32 to 122°F (0 to 50°C), this monitor automatically adjusts to provide highly accurate digital readouts. Features a dual-mount floating ring and secure suction bracket.
