Voltmeter

The voltmeter is an instrument that plays an important role in surface technology, particularly in the evaluation and control of electrochemical processes. In surface technology, voltmeters are used to measure electrical voltages between electrodes used in various coating and electroplating processes.

A voltmeter makes it possible to determine the voltage difference between a reference electrode and the surface to be coated. This voltage difference is crucial for controlling the coating process and the quality of the resulting coating. By measuring and monitoring the voltage, the thickness, composition and adhesion of the coating can be controlled.

In electrochemical coating processes such as electrolysis or electroplating, the voltmeter is used to ensure that the desired current and voltage parameters are maintained. This enables precise control of the coating process and uniform distribution of the coating on the surface of the workpiece.

The voltmeter is also used to monitor corrosion processes and evaluate the protective performance of coatings. By measuring the voltage difference between the coated surface and a reference electrode, potential corrosion risks can be detected at an early stage and appropriate measures can be taken to extend the service life of the coated materials.

Overall, the voltmeter plays an indispensable role in surface technology by offering the possibility of precisely monitoring electrochemical processes, improving the quality of coatings and increasing the efficiency of production processes.
