Do you want to measure the acidity or alkalinity of a solution? How can you get accurate measurements? Well, you can do the litmus paper test to know whether the solution is an acid or an alkaline. Anyway, litmus paper test has limitations, and for industrial purposes; you need something more reliable. The electronic device that you can use for getting accurate readings on acidity or alkalinity of a solution is called the pH Meter. It’s a simple device that looks no bigger than a digital thermometer. Well, robust designs are there for industrial purposes.
The importance of measuring pH: As mentioned, by using pH papers, you can get a rough idea about the acidity or the alkalinity of a solution. But in many industries such as food, chemical, and wine; they measure pH levels for quality reasons. For example, in the cleaning industry; the professionals measure pH of cleaning chemicals with a pH Meter before they use it on a surface. Using wrong cleaning chemicals can cause permanent damage to the surface.
pH Meter working principle: A pH Meter has two electrodes in it. One is a reference electrode and the other is a pH electrode. When you immerse the device in the solution that you want to measure, the potential difference created between the electrode displayed on the screen as the pH reading. Well, I am not going to explain it further in this article. Let’s straightway go to pH Meter uses.
* Do you like wine? Yes, everybody likes wine. Did you know that a pH Meter is essential in the winemaking process? Yes, during winemaking process; measuring the acidity level is a general procedure. Biological and chemical stability, oxidation, and color of wine – pH strongly have influences on these properties. Too little or too high acidity levels can reduce wine quality. So, the winemakers know the importance of pH Meter and pH levels during the process. General wines have a pH range from 3.3 and 3.7. Too much acidity would make it feel like you are sucking on a lime. Too little acidity would make it taste dull.
* Cleaning industry: As mentioned, professional cleaners measure pH levels of cleaning solutions before using on surfaces. Acids can damage metal surfaces. Every cleaning solution has its pH value, and that value determines whether it is safe to use or not. Some cleaning solutions have it printed on the label. So, if you are going to use a cleaning chemical on an expensive surface, make sure it will not cause any harm on the surface. In other words, if you are planning to start a professional cleaning service, then you should have a pH Meter in your account.
* Measuring soil pH: Professional gardeners know the importance of pH measuring for happy and healthy plants. Too high or too low pH levels hinder the chance for the plants to absorb available nutrients. First-time gardeners don’t know much about it, so they get it wrong for the first time. You can buy a pH Meter that can measure soil pH levels for under $50.
Other than the uses explained in this article so far, pH Meters are useful devices for the professionals in pool maintenance and cheesemaking. For example, the ideal pH level for mozzarella cheese is 5.3. Which means you need an accurate device to measure that exact pH value.
