PH
The acidity and alkalinity of drinking water, pH=7 is neutral, pH<7 is acidic, and pH>7 is alkaline.
Temperature Test
Temperature above 25°C: Temperature compensation reduces high pH and increases low pH, bringing the value closer to neutral.
Temperature below 25°C: Temperature compensation increases the pH (more alkaline) and decreases the low pH (more acidic), causing the values to move away from neutral.
