Different Types of pH Sensors- What You Should Know
One of the most crucial devices that are frequently used for water measurements is a pH sensor. This kind of sensor can determine how much acidity and alkalinity are present in water and other liquids. When utilized properly, pH sensors can guarantee a product’s safety and quality as well as the operations that take place in a manufacturing or wastewater facility.
The typical pH scale is represented by a number that can vary from 0 to 14. A material is regarded as neutral when its pH value is seven. Larger levels of alkalinity are represented by compounds with pH values above seven, whereas higher levels of acidity are thought to be present in substances with pH values below seven. For example, toothpaste commonly has a pH value between 8 and 9. Stomach acid, on the other hand, has a pH value of two.
Any business that makes use of a cooling tower, boiler, industrial procedures, swimming pool regulation, or other sorts of environmental monitoring must understand the difference between an alkaline substance and an acidic substance. The average pH of the human body is 7.4, which is necessary for the body to function properly. The body will attempt to restore to the neutral state if its composition ever shifts too much in either direction (too acidic or too alkaline).
A pH sensor will enable you to maintain pH levels at a level most suitable for the process, regardless of the application. This could be anything from caustics to powerful acids. For your application in liquid measurement, you can choose from a wide variety of distinct types of pH sensors, including combination pH sensors, laboratory pH sensors, process pH sensors, and differential pH sensors.
A reference electrode and a measuring electrode are both used in a combined pH sensor. The measuring electrode is made to detect any variations in pH value while the reference electrode is utilized to deliver a steady signal.
A metal ground electrode makes up the third of the three separate electrodes that make up differential sensors. The ability of these sensors to avoid reference fouling makes them special.
Combination sensors housed in plastic bodies and 12mm glass can be used to create laboratory sensors. For simpler tasks like pool monitoring and environmental sampling, these sensors are made.
Process pH sensors are designed in big, sturdy bodies with a process connection for continuous pH monitoring. They are constructed using combination sensors.
Before buying one of these sensors, you should fully realize that distinct types of pH sensors are designed for various uses.
