Bench-top pH meter A pH meter is an electronic instrument used to measure the pH of a
liquid (though special probes are sometimes used to measure the pH of
semi-solid substances). A typical pH meter consists of a special
measuring probe (a glass electrode) connected to an electronic meter
that measures and displays the pH reading.
The pH probe measures pH as the activity of hydrogen ions surrounding a
thin-walled glass bulb at its tip. The probe produces a small voltage
(about 0.06 volt per pH unit) that is measured and displayed as pH units
by the meter.
