If you want to measure the acidity of a liquid accurately and precise, you do not require any real laboratory or expensive testing equipment. Nowadays, the latest generation of digital pH meters have become so accurate and user-friendly, you only need to make sure your pH meter is calibrated and cared for correctly. Do not use pH testing strips or manual pH measuring instruments, these will give you an indication, but if you require accuracy use a reliable digital pH meter or pH electrode.
Remember that pH goes by a factor of 10. This means a pH level of 6, is 10x times more acidic than a pH level of 7. A pH level of 5 is 100x times more acidic than a pH level of 7. Find out more about pH here.

PH Meter applications?
PH Meters are used worldwide and on a broad scale. You will find them in any laboratory, professional kitchens, Food production, Water-treatment, Hydroponics, Pool and spa industry, Breweries, Fish-farming, Planting, and gardening…
Measuring the acidity of a liquid is an important first step in many industrial processes or analysis. For example, for pool owners it is very important to keep the pH level of their swimming pool around pH 7.2. This makes it as neutral a possible for the skin and the eyes while still maintaining a good efficiency of the chlorine. The efficiency of chlorine changes, depending on the pH level. If you care about plants you will measure the pH level of the soil and water of your plants on a daily basis. The rise of small breweries for beer and wine have also increased demand for pH meters recently. These brewers need to measure the pH of their brew and wine during the fermentation process.

Calibration of pH Meters, how and how often?
Any gel-based, liquid pH meter (this is any pH meter you see with a glass electrode bulb, filled with a liquid/gel) will require regular calibration. Why you might ask? Simply put, overtime the electrolyte gel inside of the pH meter will lose electrons and therefore its internal measuring scope changes. This will result in less accuracy and it will only get worse with the ageing of the gel.
Luckily, we can calibrate our pH meter. When we calibrate a pH meter, we will use what is known as a reference solution. This Reference solution has a fixed pH level at a certain temperature. And because we know the exact pH level of the calibration solution, we can tell the software in our pH meter exactly where that point is. If you are a regular end-user, you can calibrate your pH meter on 1 point. If you are a professional user, or you require absolute precision, you need to calibrate on 2 points.
The calibration process nowadays of a pH meter is easy and fully automatic. Just insert your pH meter into the correct pH calibration solution and start the process. For our range of Meytec® pH meters you require a pH calibration solution with a value of pH 4.01, pH 7.00 or pH 10.01. Have a look at our pH calibration solutions and order yours together with your new pH meter.
You should calibrate your pH meter as often as prescribed by the manufacturer or each time you need the most accurate pH measurement possible. Only use fresh pH buffer solution and only use it once. Find out more on how to calibrate a pH meter.
Maintenance of pH meters
Always put the protective cap back on your pH meter and store it in a dark and dry place. We highly recommend you put a few drops of KCl Storage Solution into the cap of your pH meter. This KCl Storage Solution will protect your sensitive pH electrode from drying and it prolong the lifespan of your pH meter. Never allow your pH meter to dry-out, this will cause permanent damage. Find out more about KCl Storage Solution.
End of life for a pH meter
Just like a battery, eventually the gel inside your pH meter will lose its power (electrons). When you notice your pH meter is becoming less accurate, it takes more time to stabilize a measurement, the values start changing erratically, or it won’t calibrate anymore… you will need to replace your meter. Our premium range GT-Series pH meter and pH combo meter have a replaceable pH electrode that allows you change only the pH electrode, without having to change the entire pH meter. Something to look into if you plan on using it intensively.
