PH Meter
What is PH Meter?
A PH meter is a scientific instrument that measures the hydrogen-ion activity in water-based solutions, indicating its acidity or alkalinity expressed as pH. PH meters are widely used for soil measurements in agriculture, water quality for municipal water supplies, aquaculture, environmental remediation, pharmaceuticals, food, industry, electric power, scientific research, manufacturing and many other applications.
Types of PH Meter
There are many types of PH Meter, and you can choose the right type of PH Meter based on your application scenario and usage requirements. Common types of PH Meter include pocket, portable and benchtop types PH Meters.
Features of PH Meter
Pocket PH Meter
- Inexpensive: Affordable for basic conductivity measurements.
- User-friendly: Easy to use, usually just submerge in water to read the data.
- Pocket: Small, easy to carry.

How to Properly Calibrate a pH Meter?
To properly calibrate a pH meter, you must perform at least a two-point calibration using two different buffer solutions (pH 4 and pH 7). For highly accurate pH measurements, use a three-point calibration (pH 4, pH 7, pH 10). After rinsing with distilled water, insert the pH probe (electrode) into the solution until the pH level stabilizes and the pH meter accurately matches the pH of the calibration solution.
One of the most overlooked steps in pH testing is calibrating the pH meter. Properly calibrating your pH meter is an essential step when testing the pH of a solution. This is because the electrodes in the pH probe can change over time, introducing errors. Therefore, calibration is essential to determine an accurate pH value.
How Often Should I Recalibrate My PH Meter?
How often you should calibrate your pH meter depends on your usage and the likelihood of contamination. The more you use your pH meter, the greater the likelihood of contamination and the more frequently you will need to recalibrate your meter.
We recommend that you properly calibrate/recalibrate your pH meter in the following situations:
- pH electrode is brand new
- pH electrode has not been used for a while
- You recently cleaned your pH electrode
- You need a very accurate pH measurement
- pH meter is used to measure concentrated solutions
When you first receive your pH meter, remove the pH probe from the packaging and immerse it in a cup of additive solution for at least 4 hours. Do the same if your pH probe has been dry for a long period of time. If you use your pH meter regularly, immerse the electrode in a cup of tap water for 15 minutes.
When your pH electrode no longer provides accurate readings or is no longer stable in various buffer solutions, it is time to replace your pH probe.
Applications of PH Meter
A PH meter is a scientific instrument that measures the hydrogen-ion activity in water-based solutions, indicating its acidity or alkalinity expressed as pH. Testing of pH via pH meters (pH-metry) is used in many applications ranging from laboratory experimentation to quality control.
