A pH sensor, also known as a pH probe or pH electrode, is a device used to measure the acidity or alkalinity of a liquid solution. pH is a measure of the concentration of hydrogen ions (H+) in a solution and is expressed on a logarithmic scale ranging from 0 to 14, with 7 being considered neutral. Values below 7 indicate acidity, while values above 7 indicate alkalinity.


pH sensors are widely used in various industries and applications, including environmental monitoring, water quality analysis, chemical laboratories, pharmaceutical manufacturing, food and beverage production, and agriculture. They play a crucial role in ensuring the quality and safety of products, optimizing processes, and maintaining the desired pH levels in different systems.


An ORP sensor measures the oxidation-reduction potential, which is a measure of the tendency of a solution to gain or lose electrons during a chemical reaction. It indicates the presence of oxidizing or reducing agents in a solution. ORP is measured in millivolts (mV) and represents the electrical potential difference between an electrode and a reference electrode. In water analysis, ORP is commonly used as an indicator of water disinfection effectiveness, particularly in applications using chlorine-based disinfectants.


Both pH and ORP sensors play crucial roles in maintaining water quality, optimizing processes, and ensuring the desired chemical conditions for various applications. They provide valuable information for monitoring, controlling, and adjusting chemical processes to achieve desired outcomes.
