- Versatile PH Meter: This digital pH meter is a vital tool for enhancing your quality of life. It is perfect for testing drinking water quality, monitoring swimming pools, measuring pH balance in RO/DI systems, aquariums, spas, hot tubs, wine brewing, and hydroponics. - Multi-Display Options for Salinity Testing: Easily switch between PPM, PPT, and percentage readings. For swimming pool salt tests, it measures from 0 to 9999 ppm; for seawater, it ranges from 10 to 200 ppt. Food testing is covered from 0.01% to 25%. This feature eliminates the need for complex conversions, providing straightforward results. - User-Friendly Operation: To test salinity, simply power on the meter and press the MODE button to select the SALINITY function. This intuitive design ensures a smooth user experience. - Reliable and Accurate Measurements: The digital water tester features a high-quality titanium alloy probe for quick and precise testing. With a measurement range of 0 to 9999 ppm and 0 to 200 ppt, it caters to various applications. - Comprehensive Water Testing: This multiparameter meter combines five functions—Salinity, TDS, EC, pH, and Temperature—into one device. It meets diverse water testing needs, saving you time and money while ensuring accuracy. - Performance Tips: If the display is unclear, replace the battery. For operational issues, restore factory settings by pressing and holding the power button for 8 seconds. Recalibrate with the included pH calibration powder for accurate pH readings. - Included Items: The package includes a TDS/EC/pH/temp/salt meter, pH buffer powders (4.01, 6.863, 9.18), and instructions. Note that salinity calibration requires a separate reagent. - Battery Information: Batteries come with a protective diaphragm; remove it before use. - Calibration Notes: Generally, no calibration for EC/TDS/SALT is needed—restoring factory settings is sufficient. For high accuracy, manual calibration is recommended. To restore factory settings, hold the power button for 8 seconds.
