Description: Introducing the digital pH meter, the ultimate tool for maintaining balanced and healthy plants in hydroponic systems and testing various liquids in different settings. This versatile meter provides accurate readings of pH (0.01-14.00), EC (conductivity, 0-9990S/cm), TDS (0-9990ppm), and temperature (32.0)-122.0 Fahrenheit degree, 0.0-50.0 Fahrenheit degree, making it suitable for use in hydroponic nutrient solutions, pools, spas, whirlpools, well water, filtered water, drinking water, kombucha brewing, wine and beer brewing, and more. The improved probe ensures stable readings, while the backlit LCD display allows for easy reading even in low light conditions. Automatic temperature compensation guarantees consistent results, and the automatic power-off feature conserves battery life after 5 minutes of inactivity. This pH meter also functions as a ppm tester using the standard "ppm 500" for EC conversion to meet the measurement standards of different users. It's perfect for everyday water control, with tap water at 50-150 ppm being suitable for drinking and a pH range between 6.5 and 8.5. This PPM pH meter is ideal for daily water control.
