How to Use Our Digital pH Water Testers?
It’s quite easy to use our digital pH level readers. Our pH meters are simple and handy digital devices which measure the hydrogen ion concentration in water sample with the help of a measuring probe connected to a digital meter. The devices come with a display screen. Simply follow these steps to get the right output.
- Take the water sample in a glass jar and immerse the electrode in it.
- Ensure the digital pH meter is calibrated to comparative values of known buffer solutions, usually with pH values of 4 and 7. This also depends on your application requirement.
- Also, ensure you rinse the electrode in distilled water before and after each use.
- Once you insert the probe in to the water sample or any given liquid, press the appropriate button such as calculate or measure.
- The pH values will be immediately displayed on the screen, and will gradually stabilize at one value.
- Once the value stabilizes, remove the probe and rinse it again in distilled water.
- Clean the electrode using a napkin and store it in an acidic buffer solution when not in use.
Working and Structure of Our Digital pH Meters or Testers
Here are some pointers on the working and structure of our pH meter for water treatment processes.
- pH is the hydrogen ion concentration in a fluid, and its measurement is based on the activity of hydrogen ions rather than the molar concentration.
- A digital pH meter has a display, responsive and referral electrodes, and a user-friendly menu.
- The electrode possesses internal and external tubes, wherein the internal tube has calibrated values, while the external tube is made of pH sensitive glass.
- The measuring probe is usually a glass electrode or an ion-selective transistor. The electrode is sealed at the end with a bulb-like structure.
- This glass electrode when immersed in the solution develops a charge that relates to the ions’ activity in the sample.
- The electrodes produce a very minor voltage and the difference in values is noted. Thus, the change in the potential difference is measured and compared with the reference values which are pre-calibrated.
