Hoe kalibreer je een pH meter?

In this video I’m going to show you how to calibrate a pH meter. This is what we need: The manual, the pH meter itself, calibration fluid in 7.00 and 4.01 We turn the meter on, Put it in the water for a while and we start with 7.0. As soon as you see the smiley appear, press calibration again. Now it is calibrated at 7.00 Now we take the 4.01. We let it search until we see the smiley showing up again and press again. The pH meter is now calibrated.
