How to use your Water Rangers pH meter
The pH meter needs to be calibrated to ensure accurate measurements. Without calibration, the meter readings can drift over time, leading to inaccuracies. If you are testing daily, the meters should be calibrated at least once a day.
- Rinse the sample cup three times before taking the final sample for the measurement. If possible and safe, you can also dip the meter right into the waterbody.
- Dip the meter into the water and wait for the number on the screen to stabilize before recording the number. You can even press the “HLD” or the hold button to freeze the reading so you can take notes without it changing.
- Since pH is affected by water temperature, you should also use this to record water temperature.
- After the measurement, rinse the probe with distilled water before the next measurement or before storing it.
