pH calibration to your water
In India, water changes from one street to the next. Borewell, tanker, municipal and RO water all have different TDS and minerals, so one factory setting cannot give the same result in every home. That is why AlkaFresh has pH calibration: our engineer measures your water and sets the ionizer for it, so the pH you select on the display is the pH you actually get in your glass.
- Your water's TDS and hardness are measured at installation
- The ionizer is set for your home's water, not an average
- If your water changes, we re-calibrate it over Wi-Fi
