1.Advanced Pool Water Quality Tester: The intelligent chlorin meter provides an solution for monitoring pH and salinity levels in seawater pools. Simplifying the process of ensuring proper level balance, it helps maintain optimal pH and chlorin content for efficient chlorinator operation. 2.pH and Free Chlorine Monitoring: Accurately measure pH and free chlorine concentration to maintain a healthy swimming pool environment. Keep pH between 7.2 to 7.8 and chlorine concentration between 1 to 3 mg/L. This dual function ensures clear, safe water for swimmers. 3.Wireless App Control: Combine modern convenience with wireless connectivity using the solar floating swimming pool water quality tester. Monitor pool data in real-time through the app and set alerts for immediate corrective measures when parameters deviate. 4. Multifunctional Monitoring: The device measures seven critical parameters: pH, ORP, salinity, chlorine, EC, TDS, and temperature. Its wide range and high accuracy suit pools, including above-ground, in-ground, seawater, and hot tubs. 5.Convenient and User-Friendly Design: Solar powered swimming with USB charging makes it ideal for outdoor pools. The floating design ensures continuous, hassle-free measurement, supported by easy app calibration for quick adjustments. pH Range: 0.0-14.0 Resolution: 0.1 pH Accuracy: 0.1 pH Chlorine Range: 0.04.0 mg/L Resolution: 0.1 mg/L Accuracy: 0.1 mg/L Salinity Range: 0-999 ppm, 1000-9990 ppm Resolution: 1 ppm, 10 ppm Accuracy: 2% EC Range: 0-2000 S/cm, 2000-9990 S/cm, 10.01-19.9 mS/cm Resolution: 1 S/cm, 10 S/cm, 0.01 mS/cm Accuracy: 2% TDS Range: 0-999 ppm, 1000-9990 ppm Resolution: 1ppm, 10ppm Accuracy: 2% ORP range: 999mV Resolution: 1mV Color: As Shown Material: ABS Package Contents: 1 x water quality tester 1 x auxiliary tool Only the above package content, other products are not included.
