7-in-1 Digital Water Quality Tester for pH, TDS, EC, ORP, Salinity, Specific Gravity & Temperature – Backlit LCD Display – Aquarium, Pool, Hydroponics, Drinking Water

7-in-1 pH Meter: The pH meter is designed with a 7-in-1 function. This allows you to measure pH (acidity and alkalinity), EC (electrical conductivity), TDS (total dissolved solids), salinity, S.G (specific gravity), ORP (oxidation-reduction potential) and temperature. Versatile Salinity Testing Modes: The pH meter provides 3 salinity testing options. This includes salinity testing (0-9999 ppm), seawater testing (10-200 ppt), and food testing (0.01-25%). TDS and salinity have the same units, therefore when measuring salinity, the pH meter needs to be converted to salinity mode to ensure accurate and reliable results. Automatic pH Calibration: The pH water tester is equipped with a highly sensitive glass probe. It delivers a complete measurement range from 0-14pH with a 0.01 pH resolution. This water pH meter employs a 3-point calibration method to calibrate the electrode to solutions of pH 4.00, pH 6.86, and pH 9.18. Measurement accuracy is easily ensured through simple calibration. Widely Used: The 7-in-1 pH tester is the perfect solution for testing various environments, including home drinking water, hydroponics, swimming pools, aquariums, laboratories, etc. pH Measurement Range: 0-14 pH Resolution:01 pH Temperature Compensation: Automatic, with ATC Display: Large LCD for clear visibility Calibration: 3-point (pH 4.00, 6.86, 9.18) Enhance your water testing practice with our versatile and precise hydroponics pH tester. Ideal for a variety of environments, this pH meter simplifies complex testing tasks with its multi-functional capabilities and easy calibration process. Ensure the health and safety of your aquatic systems and water supplies with a tool designed for accuracy, efficiency, and reliability.
