Take Care Of Your pH Meter For Accurate Readings
A pH Meter is an electronic device used for measuring pH of a solution. Well, you must have learned about pH and its importance in school-days. The power of Hydrogen is denoted by pH. I know; in schools, we didn’t use a pH Meter. Litmus paper is the testing agent that we used in school for determining the acidity or the alkalinity of a solution. Anyway, for industrial and commercial applications, the litmus paper test is not accurate enough. On the other hand, we don’t have time to be performing the litmus paper test when it comes to commercial and industrial applications. OK, let’s get to know about the pH Meter a bit better. Anyway, I am not going to spend many words to explain it here. The electrode and the LCD screen are the main components of a pH Meter. The electrode is the main component of the device that measures pH of the solution being measured. The electronics in the device then converts the created voltage into data that we see on the LCD screen.
* It is imperative that you maintain the pH Meter well for accurate readings. Poor maintenance is the main reason for false readings. Let’s talk about the electrode. As mentioned, it is the main component of the device, and it is a very sensitive component. To protect the electrode from drying out, keeping the probe submerged in a liquid is a must. The electrode of the pH Meter should be kept hydrated all the time. And failing to do it will permanently disable the electrode. Well, you can’t keep it submerged in diesel. The type of solution you will need to keep the electrode hydrated will depend on the type of your meter. Keeping the electrode submerged in distilled water for longer periods is not advisable.
* Clean the meter regularly: Cleaning the probe after every use is highly advisable. Remnants of whatever you measured and dust can damage the electrode. OK, if you forgot to clean the meter after using, and if crystallized remnants are formed on the electrode; getting it professionally serviced is the only option you will have. Be aware of the solution that you will need to clean the electrode after every use. Read the leaflet that comes with the device for more information. Distilled or deionized water is the popular cleaning solutions for pH Meter.
* Calibrating the meter: Regular calibration is important for consistent and accurate readings. Well, most users ignore calibration as they find it time-consuming. Obtaining accurate readings is the whole purpose of using a pH Meter. If not, we can use litmus paper to determine the acidity or the alkalinity of a solution. Which means, you should never ignore calibration of the device. An error in pH readings can lead to a big loss (especially, in the food industry as bacteria can grow under certain pH conditions.)
Well, you can’t use your device forever. With time, its components will start to die. Replacing the whole device is the best option you got in this case. Anyway, a pH Meter is not a very expensive device. Just make sure to buy it from a leading manufacturer. If you maintain the device properly; it will serve you for months.
