In the reviews below you will learn the best pH meters to buy currently.

A pH meter is an electronic device used for measuring the acidity or alkalinity (pH) of a liquid. The pH reading itself is on the “pH scale” from 1 to 14, with 1 being the highest acidity and 14 being the maximum alkilinity. The neutral point – or zero pH – is 7. A pH meter consists of an electronic meter with a special glass measuring probe connected to it, it measures the pH and gives the the reading on an LCD display. pH meters generally require to be calibrated using control solutions which have precise pH values. There are many uses for the pH meter, both scientific and industrial, as well as normal everyday household applications. These include: Fish ponds (koi carp), plants and gardens, swimming pools, soil analysis, home-brewing, home winemaking, testing well water, testing chemical baths, hydroponic gardening, cheese making, spa baths, drinking water, foodstuffs.
