NOYAFA EZ9901 TDS Unboxing Video
The acidity and alkalinity of drinking water, pH=7 is neutral, pH<7 is acidic, and pH>7 is alkaline.
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.
TDS value represents the totalsoluble solids content in water
The lower the TDS value, the lessthe ion content in the water, andthe higher the purity of the water
