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.

012-06832A pH Sensor Using the pH Sensor Calibrating the pH Sensor ➤ Note: Use buffer solutions that are at a temperature similar to the temperature of the sample to be measured. Connecting the pH Sensor to the interface box 1. Connect the 8-pin DIN plug of the pH Sensor amplifier box into analog channel A, B or C of the computer interface (Figure 1a). or Use the supplied cable to connect the pH electrode amplifier box to the analog channel of the interface box (Figure 1b). a Two Buffer Method: 1.

012-06832A pH Sensor Electrode Storage Taking a pH Measurement 1. Rinse the pH electrode in distilled water and place it in the sample to be measured. The pH Electrode should not be stored dry and should be stored as follows: 2. In the Experiment Setup window, set up a data display (such as the Graph display) and begin recording data. Short Term Storage (up to one week): store in a pH 4 buffer solution or tap water.
