HALO's smart system tells you when your electrode needs cleaning or calibration. Organize and share your results. Group your data by time or notation.
A pH meter is a scientific instrument that measures the hydrogen-ion activity in water-based solutions, indicating its acidity or alkalinity expressed as pH. The pH meter measures the difference in electrical potential between a pH electrode and a reference electrode, and so the pH meter is sometimes referred to … Visa mer The rate and outcome of chemical reactions taking place in water often depends on the acidity of the water, and it is therefore useful to know the acidity of the water, typically measured by means of a pH meter. … Visa mer In general there are three major categories of pH meters.
