A pH Meter is a versatile device that is being used in many industries today. It is a digital device, so measurements can be taken easily with it. In this article, I am explaining common mistakes that people make when using this versatile device. Anyway, using a pH Meter is not rocket science. What would go wrong then? Don’t worry! You will get the answers here.
Let me explain you the advantages of a pH Meter first. I know that you can remember the Litmus Paper Test that you did in school. The litmus paper test is also can be used for determining acidity or alkalinity of a solution. By matching the color change with the given chart, you determined the acidity or the alkalinity of the solution. Anyway, can you rely on the Litmus Paper Test in the food industry? When it comes to industrial applications, a litmus paper test is not reliable. The digital device called the pH Meter is the recommended device for determining pH levels in many industries.
People often make mistakes when using a pH Meter, and below is a list of common mistakes:
* Improper electrode storing: The electrode is the most important component in a pH Meter, and it is a sensitive component. When not stored properly, an electrode can get damaged or begin to give inaccurate readings. The electrode of a pH Meter is designed to be stored in the storing solution. Failing to do it will lead to a dry electrode. The gel inside the electrode is the one that gives the electrode the ability to detect pH changes. So, when the inside gel is dried out, the sensitivity of the electrode will be gone sooner or later. Never make that error if you want your pH Meter to give you accurate readings and serve you for months.
* Filling to clean the electrode: When you immerse the electrode in a solution, and if not cleaned well after use; deposits can form on the sensing glass of the electrode. Make sure you clean the electrode with the right electrode-cleaning solution. Did you know that cleaning the electrode is equally important as pH Meter calibrating? Failing to clean the electrode will lead to oil and fat buildups on it. So, at the end of the day; the device will begin to give inaccurate readings. When it comes to the food industry, inaccurate pH readings can lead to disasters.
* pH Meter calibration: Don’t calibrate the device with any other solutions other than pH Meter calibrating buffer solutions. Also, depending on the solution that you are going to measure the pH of; choose the right calibration buffer solution.
* Not replacing the electrode: pH Meters come with replaceable electrodes today. Buying a pH Meter that comes with a fixed electrode is not advisable as you will have to replace the whole device, in case of electrode damage. Well, nothing in this world is permanent. You can’t use the same electrode forever. If you use the device more frequently, then the electrode will get aged sooner. With time, the accuracy of the electrode will go down, so replace it.
Summation: Avoid these common errors when using your pH Meter. Poor maintenance of the device is the most common reason behind inaccurate readings.
