pH-mètre -> pH meter

Un pH-mètre est un appareil souvent électronique permettant la mesure du pH d'une solution
Wikipédia

A pH meter is an electronic instrument used to measure the pH (acidity or alkalinity) 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.
