Abstract:   (1684 Views)
Evaluations of the acidity or alkalinity of solutions are used in many industries such as food industries, medicine, chemical engineering, petrochemical industries, agriculture, animal husbandry, industrial laboratories, etc. Portable and stationary pH measurements are very common and are an integral part of these studies, due to the importance of pH. In most of these evaluations and studies, a solution with the preferred pH magnitude must be prepared. Therefore, it is necessary to have a device that can instantaneously control and reset the pH of the solution. In this study, a pH meter equipped with an automatic pH regulator by instant feedback method is described.
This system was designed and constructed to create an automatic pH regulator without manual intervention for toxic and dangerous solutions, which could accurately adjust the desired pH in the shortest possible time. The automatic pH adjustment system is equipped with a pH measuring unit that can instantaneously present the pH of the solution. The user determines the desired pH value and the system decides to use the acid or alkaline reference tanks to reach the target point. These operations can be done in a fully automated or manual manner. The error (tolerance) of the automatic pH adjustment of the solution is 0.02, which is very small in the pH evaluations.
Keywords: pH, pH meter, automatic pH adjustment of the solution, pH adjustment of the solution by instant feedback method
