The surface pH meter PCE-228SF is used to measure the pH on surfaces such as paper, cardboard, leather, textiles and skin. The pH and temperature can be stored directly on the SD card. The special pH electrode of the pH meter PCE-228SF is particularly flat and made of epoxy, which makes the pH electrode particularly resistant to impact. Temperature compensation is either manual or automatic via the supplied temperature sensor.
In addition to the measurement of the pH value of surfaces, the pH meter can also be used to measure very small sample volumes from 0.1 ml upwards. For this, the surface pH meter is supplied with a special measuring cuvette. This cuvette can be plugged directly onto the electrode of the pH meter.
