WebbBelow, is more information on the pH of milk and why it should be measured. What is the pH of milk? The pH value for fresh raw milk is normally in the range of 6.4 to 6.8 and depends on the source of the milk. Why is it important to measure the pH of milk? The pH of milk accounts for the amount of lactic acid produced by microbial activity. WebbpH meter, electric device used to measure hydrogen-ion activity (acidity or alkalinity) in solution. Fundamentally, a pH meter consists of a voltmeter attached to a pH-responsive electrode and a reference (unvarying) electrode.
WebbThe pH meter measures the difference in electrical potential between a pH electrode and a reference electrode, and so the pH meter is sometimes referred to as a “potentiometric pH meter”. The difference in electrical potential relates to the acidity or pH of the solution.The pH meter is used in many applications ranging from laboratory ...
