This 8-in-1 professional soil testing device simultaneously monitors pH, moisture, fertility, conductivity, salinity, air humidity, light intensity, and temperature. Suitable for greenhouses, lawns, gardens, hydroponics, indoor potted plants, and even pool water quality testing, it adapts to all-scenario environments.The device supports dual soil-liquid detection, meeting the needs of gardeners for monitoring soil fertility and hydroponic nutrient solutions, while providing accurate pH and salinity data for pool maintenance. Its 45° tilted screen design enables intuitive reading of light lux values, paired with Automatic Temperature Compensation (ATC) to precisely measure temperature and humidity, scientifically optimizing plant growth conditions.Via Bluetooth connection to the dedicated app, all detection data syncs in real-time for centralized viewing on mobile devices. The device stores 1,000 historical records for sharing, and includes a pH calibration kit to ensure accuracy. When values exceed normal ranges, the app triggers red alerts for intelligent plant care management.
