A pH meter is an electronic piece of equipment to determine the pH of a solution. An electrode (usually glass) is attached to the meter, which measures the voltage. As pH meters and probes require calibration before use, they can be calibrated with a standard buffer solution that is input into the machine (or it can be done without a solution) giving an accurate result. The buffer solution commonly uses the following three pH levels: pH 7, pH 4, and pH 9.2/10.

A pH meter works by associating a voltage with a pH value. The more ions that pass through the membrane, the higher the pH value, and vice versa.


How Accurate Is A pH Meter?

pH meters use a computer or digital user interface providing you with an instant pH reading on a readable display, therefore, they are considered extremely accurate and durable as long as you store them properly and maintain them according to the manufacturer’s guidelines.

As mentioned, pH meters must be calibrated using a standardized buffer. A buffer allows the meter to associate the voltage of a solution with a pH value. pH meters may slightly differ, but they are usually all accurate to the hundredth place. pH meters can be affected by ion interference sometimes drifting from the calibration position, hence it is important to always calibrate your pH meter before use.

Some pH meters require to be plugged into an outlet, while others need batteries, which are commonly used in the field. pH meters accommodate different industries depending on the application.


Advantages Of Using pH Meters

pH meters are simple to use and are not affected by human error such as color blindness. Some people may perceive color differently from others, or the true result. As pH meters use a readable digital display, they provide a much more precise result than pH papers and titration methods.


As pH meters are portable, providing quality precision readings wherever you need to test pH solutions is easy. They can be used in a controlled laboratory or used for environmental field-testing. If you will be in the field, small battery-operated pH meters are ideal for hauling to different locations.


Disadvantages Of Using pH Meters

pH meters cost a lot more money than pH paper strips, as a pH meter is a long-term investment to provide accurate pH readings. If you only need to take occasional pH readings such as in home aquariums, pH paper may be a better alternative.


Another disadvantage of using pH meters is maintenance. You will need to clean it regularly to avoid possible contamination of samples. As most pH meters contain a probe with a glass tip, these are extremely fragile so can be easily broken or damaged if exposed to corrosive substances.


Lastly, pH meters must be calibrated before use, which is vital for obtaining accurate results. If a pH meter is not calibrated properly, the results can be distorted. To prevent human error when using a pH meter, always refer to the operating manual for detailed instructions of use.



Why calibrate your pH meter and how!

When it comes to measuring pH you deserve good data. In order to obtain accurate pH data you need to calibrate well and often. In order to obtain precise pH measurement a calibration should be performed before each measurement. In saying this, sometimes this is not feasible and a good rule to abide by is to calibrate at the beginning of each day. This will offer you repeatable results with a high degree of accuracy.


What is calibration?

A pH calibration is the process of adjusting your Manual Calibration PH Meter by measuring solutions of a known pH value. This is because the characteristics of your electrode will change over time and this needs to be compensated for. A calibration does this by matching your pH meter to the current characteristics of your pH sensor.
