Calibration solution or Buffer for PH Meter and EC Meter

PH Calibration Solution and PH Buffer for PH Meter and EC Meter

PH Meter Calibration

A pH meter is a very sensitive measuring instrument. If you want the most accurate measurements, you will need to calibrate your pH meter regularly. It is advised to calibrate your pH meter every 2 weeks, or every time you want the most accurate measurements. Don't worry, the calibration of your pH meter is a very easy procedure. 

PH Meters are calibrated with a special pH calibration solution or also known as a pH buffer. This calibration solution has a known, and fixed pH value. You have different pH calibration solutions because some models require a specific pH level. Always check the instructions of your pH-meter. It is important to calibrate your pH meter with the correct pH buffer.

How to calibrate a pH meter?

  1. Make sure you have the correct calibration solution for your pH meter. Fill a clean cup, deep enough so that electrode of your pH meter is completely immersed.
  2. Turn on your pH meter and place your pH meter in the cup.
  3. Stir gently and wait 1 minute for the measurement to stabilize.
  4. Use the mini-screwdriver to increase or decrease the pH level on the display of your pH meter, until the pH value on your screen matches the pH value of your calibration solution.
  5. (for automatic calibration, u usually have to press the calibration button for 5 seconds. The pH meter will automatically recognize the pH buffer)
  6. Your pH meter is now calibrated and ready to be used.


PH calibration solution or pH Buffer

There are 2 kinds of pH calibration solutions or pH buffer available. You have liquid calibration solution that is specifically designed to have a specific fixed pH level. This sort of pH buffer is very easy to use because you can use it straight-away. 

Our pH calibration solution:

  • PH Calibration solution pH4.01
  • PH Calibration solution pH7.00


The second type is PH Buffer Powder. This a special powder that you need to dissolve in 250ml of distilled water. Open the package, put the powder in 250ml of distilled water and stir until it is completely dissolved. Wait 5 minutes to make sure that the powder is dissolved and stir well. You can only use this liquid one time. 

We have a large selection of pH buffer powder available:


EC Meter calibration

Your EC Meter requires less calibration than a pH meter. It measures the conductivity of a liquid and works completely differently than a pH meter. EC meter calibration solution has a fixed conductivity level. Always check the instructions of your EC Meter, you will need the correct EC Meter buffer. The calibration process of your EC Meter is very easy. follow our steps on how to calibrate your EC Meter. We recommend calibrating all the EC meter on our website with 1.143 calibration solution.

How to calibrate a EC meter?

  1. Make sure you have the correct calibration solution for your EC meter. (EC 1.143 for our meters) Fill a clean cup, deep enough so that electrode of your pH meter is completely immersed.
  2. Turn on your EC meter and place your EC meter in the cup.
  3. Stir gently and wait 1 minute for the measurement to stabilize.
  4. Use the mini-screwdriver to increase or decrease the pH level on the display of your pH meter, until the EC value on your screen matches the EC value of your calibration solution.
  5. (for automatic calibration, u usually have to press the calibration button for 5 seconds. The EC meter will automatically recognize the EC buffer)
  6. Your EC meter is now calibrated and ready to be used.

EC calibration solution or EC Buffer

EC calibration solution or EC buffer is a specially designed liquid to calibrate your EC Meter. The EC calibration solution has a fixed conductivity level, so that you can easily calibrate your EC meter to this point.

Our EC calibration solution:

  • EC Calibration solution EC 1.413
  • EC Calibration solution EC 12.88
