Summary
[edit]
| Description |
Digital pH meter: Digital 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 difference in electrical potential relates to the acidity or pH of the solution. A pH meter takes advantage of this and works like a voltmeter: it measures the voltage produced by the solution whose acidity we're interested in, compares it with the voltage of a known solution, and uses the difference in voltage. |
