iSOLV APH480 is a pH meter 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 as a "potentiometric pH meter". The difference in electrical potential relates to the acidity or pH of the solution. The pH meter is used in many applications ranging from laboratory experimentation to quality control.

The controller iSOLV APH480 can be configured to measure pH or ORP during the installation. It provides manual and automatic temperature compensation, if an RTD Pt100 or an RTD Pt1000 is connected. When the RTD is connected, the instruments provides the temperature reading.
