Introduction
The PASCO CI-6507A pH Sensor (pH electrode and
amplifier) is designed to be used with PASCO
ScienceWorkshop computer interface systems (300,
500, 700, and 750).
The pH electrode connects to the amplifier box with a
BNC connector, and the amplifier plugs into the
interface box directly or via a connecting cable.
The pH electrode is a standard type, producing an
electrical potential difference depending on the
hydrogen ion concentration (potential of hydrogen) in
a solution. The pH electrode is stored in a small plastic
container that contains a pH 4 buffer solution.
The pH amplifier translates the potential differences
measured by the pH electrode into the voltages
required by the Science Workshop interface. The
amplifier allows any standard pH electrode to be used
with ScienceWorkshop.
