A pH meter is an instrument used to measure the acidity or alkalinity of a solution. The measuring range of the PH meter that we measure is always between 0-14. It is important to know that the lower this number is - the higher the acidity level. Below 7 are acidic values while above 7 basic values. Measuring the acidity of a digital PH meter is a quick and accurate way to measure it. Very convenient and simple to read digital display results. Based on the effect of acidity on the electrical properties of the solution. Electronic pH meters are considered to be very accurate. Before each measurement, calibrate the instrument with three calibration liquids 4, 7, and 10.
