The Waterproof Portable pH Meter is a sophisticated device that measures the acidity or alkalinity of a solution. The working principle of this device is based on the measurement of the concentration of hydrogen ions in a solution. The pH meter consists of a glass electrode and a reference electrode, which are immersed in the solution to be tested. The glass electrode measures the hydrogen ion concentration, and the reference electrode provides a stable reference potential. The difference in potential between the two electrodes is measured and converted into a pH value using a digital display.

One of the advantages of using a Waterproof Portable pH Meter is its accuracy. The device is calibrated to ensure that it provides accurate and reliable measurements. It can measure pH values from 0 to 14 with an accuracy of ±0.01 pH units. This level of accuracy makes it suitable for use in scientific research, environmental monitoring, and quality control applications.
