2PCS Water Quality Tester, Electronic pH Meter Tester, TDS&EC Meter Temperature, 4 in 1 Water Quality Tester with LCD Display, High Accuracy Resolution 0.01, for Swimming Pool, Drinking Water

General description 2PCS Water Quality Tester is a versatile electronic device designed to measure pH, TDS (Total Dissolved Solids), EC (Electrical Conductivity), and temperature in various water types. It is suitable for testing tap water, filtered water, distilled water, bottled water, well water, and fresh water. This 4-in-1 water quality tester is fast, reliable, and easy to use, providing results in seconds without the need for calibration or setup. Technical specifications Measuring Range: pH 0.00 - 14.00 Resolution: 0.01 pH Accuracy: ±0.01 pH Automatic Temperature Compensation: 0 - 60°C / 32 - 140°F Dimensions: 15.5 x 3 x 1.5 cm (pH Meter), 15.4 x 3.1 x 1.4 cm (TDS/EC Meter) Weight: 50 g (pH Meter), 59 g (TDS/EC Meter) Battery: 2 x 1.5V LR44 (pH Meter), 3V CR2032 (TDS/EC Meter) - batteries included Operating Temperature: 0°C to 60°C Calibration Automatic calibration at two points using included calibration powders (4.01 and 6.86 pH) Calibration process involves immersing the electrode in standard buffer solutions and pressing the CAL button Calibration should be performed with distilled or pure water only Usage To use the water quality tester, simply dip the meter into the water sample, stir gently, and wait a few seconds for the reading to stabilize. The easy-to-read LCD display will show the results promptly. For pH testing, remove the protective cap, press "ON/OFF" to activate, and follow the calibration instructions for accurate measurements.
