USE OF pH METER. Rules: The electrode should be in solution when it is “ measuring” pH. When out of solution, it should be in stand-by mode. Keep the
pH Meter: Amazon.com pH Meter. A pH meter, also called a pH tester, measures the acidity and alkalinity of a liquid or other substance, on a scale with a range of 0 to 14, where 7 is neutral, 8 to 14 alkaline, and 0 to 6 acidic. pH meters … The Guide to pH Measurement in Food and Drink 6 The Guide to pH Measurement in Food Drink pH can be measured one of two ways: By litmus paper, (sometimes referred to as pH test strips) or by a pH meter and electrode. TEST STRIPS VS. PH METER … What is a pH Meter and How Does it Work? Feb 14, 2020 · pH is a measurable parameter between the values of 0 and 14, provided the concentration of the solution does not exceed 1M. Solutions with a pH<7 are acidic, whereas those with a pH>7 are alkaline. A pH meter …
