5-in-1 electronic pH tester for testing pH, TDS, EC, temperature and salinity, suitable for drinking water and swimming pools

💧[Five-in-One Multifunction] - This digital pH meter has five functions for testing water pH, total dissolved solids (TDS), conductivity (EC), salinity, and temperature. Measurement ranges: pH 0.00-14.00 (accuracy of 0.01 pH), TDS 0-10,000 ppm, 10.1-200.00 ppt, EC 0-10,000 µS/cm, 10.1-19.99 mS, 20.1-400.0 mS/cm, salinity 0.01%-25.00%, and temperature 0-60°C. Waterproof rating: IP67.

💧[High-precision pH tester] - The glass probe of this pH tester features a low-resistance (25 MΩ) glass sensitive membrane with a 0.1-second response time. The TDS electrode is made of high-quality, flexible titanium alloy for excellent corrosion resistance. This pH meter uses a three-point calibration method, calibrating the electrode on pH solutions of 4.01/6.86/9.18 to ensure accurate measurements.

💧[Green backlit LCD screen] - This pH meter features a clear and intuitive green backlit LCD screen. The digital display remains readable even in low light. Its pocket-sized design makes it easy to carry. The automatic shut-off function after 5 minutes saves energy and extends battery life. [Automatic Temperature Compensation and Calibration] - Liquid temperature can affect measurement values, but our digital water pH tester can accurately measure the pH of samples within a temperature range of 0°C to 60°C (32 to 140°F). The pH tester automatically recognizes the calibration solution for easy reading. [Wide Application] - This 5-in-1 multifunctional pH tester is ideal for home and laboratory pH testing applications and can be used to test the quality of drinking water, swimming pools, aquariums, spas, aquaculture, ponds, and well water indoors or on vacation, ensuring water safety in daily life.
