How does ph tester work
WebpH strips are pieces of paper that change color depending on the pH – the acidity or alkalinity – of a liquid. pH strips are a cheap and relatively accurate way of measuring the pH of any liquid, in our case urine. A strip of filter paper is soaked with different pH indicators (more on that later), allowed to dry and voila: pH strips. WebDec 20, 2024 · 1.Clean the prongs of the tester with distilled water and a clean cloth before use, and between uses. This will keep the readings from being affected by the pH of a previous test or tap water. 2.Insert the prongs into the soil you wish to measure.
