Does my new pH meter come calibrated?
In case of electrode dehydration, or possible jostling during shipping, Hanna recommends you calibrate your meter before using it.
When you receive your new pH meter, before measuring, make sure your electrode is hydrated and calibrated using the provided sachets before taking your first measurement. Always calibrate to at least two calibration points.
