Four-in-one digital pH meter, suitable for multiple environments, multi-functional and high-precision KFD

1. Four-in-one multifunctional measurement: The pH meter can measure pH value, electrical conductivity (EC), total dissolved solids (TDS) and temperature. Just press the {Mode/Calibration} key to switch the readings of pH, EC and TDS. 2. Easy-to-use pH tester: Simply immerse the electrode of the water quality pH tester into the target solution. After the reading stabilizes, long-press the "Hold/Temperature" button and then read the data. Before using the pH meter again, please carefully clean the probe to avoid affecting the reading. 3. High-precision water quality pH tester: Equipped with a highly sensitive probe, one can quickly read the measurement results. This four-in-one pH tester has a wide measurement range and high resolution, and can measure various different liquids. 4. Automatic temperature compensation: This water quality pH tester has an accurate automatic temperature compensation (ATC) function. The pH/TDS/EC/temperature functions can accurately read the sample values in a wide temperature range of 32°F - 140°F, effectively solving the problem of inaccurate measurement caused by the change of liquid temperature. 5. Water quality tester with backlight display: One can clearly see the data even in a dark environment. The green backlight display makes it easy to read the data of the pH, TDS and EC meters at different angles and in low light conditions. Press the "Hold/Temperature" key to lock the reading for easy recording. 6. Multifunctional pH tester: This digital pH tester is widely used in deep water culture (DWC) hydroponic systems, deionized water, drinking water, tap water, beer, wine, kombucha, milk, home brewing, swimming pools, aquariums, reef tanks, hot tubs, aquaculture, spas, fish tanks and urine testing, etc. 7.
