Ph meters
pH meters are valuable analytical devices, indispensable for a multitude of sectors in science and industry. First, to understand how a pH meter works, it is necessary to understand what pH is. The pH is a measure of the acidity or alkalinity of a solution, expressed on a scale from 0 to 14.
But how is this measurement performed? The key factor in the operation of these meters is the glass electrode, the main part that allows the concentration of hydrogen ions to be differentiated. When this electrode is introduced into the solution to be analyzed, a potential difference (voltage) proportional to the pH of the solution is generated. This voltage is translated into a pH reading by the meter, thus allowing accurate quantification.
Types of pH meters a Laboratory may need
Industrial pH controller
PH meter: this instrument is capable of measuring the acidity or alkalinity of a solution. It is used in the laboratory by precise analysis, through polarized glass plates, sensitive to hydrogen ions. Their measurements range from 0 to 14, with the lowest value being the most acidic and vice versa. And it is used in many applications ranging from laboratory experimentation to quality control analysis.
In all laboratory work, measurement is part of the means that are carried out in the day to day, since in many cases, it is necessary to calculate exactly certain substances, or to study perfectly, the type of element that makes up a mixture. Therefore, the equipment for measuring PH, ions and conductivity are essential in these practices.
Portable
A standard pH meter consists of two important parts: the glass electrode and the display unit.
The electrode is the spearhead of pH measurement. At the microscopic level, the thin glass layer of the electrode interacts with the hydrogen ions in the solution, generating a potential difference measured by the meter.
The display unit, on the other hand, is the interface through which we visualize and understand the data. It converts the electrical signal from the electrode into a pH reading that can be easily interpreted. Some advanced meters also offer additional features, such as temperature compensation and calibration functions.
