How often do I have to recalibrate the Skin-pH-Meter probe?

This depends on the frequency of usage and the state of the probe (age). If the probe is used frequently, we recommend recalibrating every 4 weeks. With the supplied buffer solutions you can also check the accuracy of the probe.pHelectrode

Which concentration has the KCL solution if I have to replace it?

The concentration is 3 mol/l of KCl solution (potassium chloride) which can be ordered over pharmacies. For mixing it put 224 g of KCl into a bottle and fill up to 1 l.

With what kind of liquid do I have to refill the liquid inside the probe, if necessary?

The liquid level of the electrolyte at the outer-shell electrode must be approx. 10 mm below the filling-aperture. If necessary (earliest after 6 months operation) the electrolyte can be refilled through the filling-hole covered with the red rubber cap (3 mol/l KCl/AgCl ).
