6 in 1 pool monitor Test pH, chlorine (CL), electrical conductivity (EC), total dissolved solids (TDS), oxidation-reduction potential (ORP), and temperature with a single device. It uses a high-sensitivity glass probe for accurate and reliable detection. Bluetooth connection and data management Real-time Bluetooth transmission enables easy saving, management, and sharing of test data without worrying about data loss. The large LCD screen can display multiple parameters at the same time, and the mobile app can control the backlit display for easy viewing. Customizable parameters Parameters can be customized through the mobile app. You can set upper and lower limit values, and if a value exceeds the test range, the app will display a red value to prompt you. Suitable for swimming pools, domestic drinking water, hydroponics, laboratories, and aquariums. Main parameters PH: 0.1-14.0 CL: 0.1-4.0 mg/L EC: 0-1990 μS/cm, 2000-10000 μS/cm, 10.01-20.0 mS/cm TDS: 0-999 ppm, 1000-9990 ppm ORP: -1200 to +1200 mV Temperature: 0.1 C to 80.0 C, 32.1 F to 176.0 F Chlorine: .PH: 6.8 4.0 9.2 or 7.0 4.0 10.0 EC TDS: 1413 μS/cm, 12.88 mS/cm ORP: 256 mV Applications and use scenarios - Home swimming pool maintenance: monitor pH, chlorine, EC, TDS, ORP, and temperature in real time; use app alerts to maintain water quality. - Hydroponics and nutrient solutions: track pH, EC, and TDS to keep growing conditions stable. - Aquariums and aquatic systems: ensure safe water parameters for fish and plants with continuous monitoring and remote data access.
