pH meter

 

Name of equipment:

pH meter

Purpose:

A pH meter is an electronic instrument used to measure the pH (acidity or basicity) of a liquid (though special probes are sometimes used to measure the pH of semi-solid supstance).

Model, type, country of origin:

MA 5736, Metrel (Iskra), Slovenia

Technical characte-ristics:

Measuring range: 0.000 - 14.000 pH; 0,0 - 99,9 0C; -1999,9 do +1999,9 mV

Year of origin:  -

Method of
work:

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 surrounds 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 the pH units by the meter.
