A pH meter measures the acidity or alkalinity of a substance by checking the ratio of positively charged protons to negatively charged electrons using a probe. A portable meter allows you to accurately check the pH of a sample outside of the lab. This comes in handy for environmental studies such as those measuring water and soil quality. When purchasing a handheld pH meter, it is important to check the range of measurement, how the measurements are taken and whether extra functionality is needed, such as the ability to load data directly onto a computer or phone.
