The ph value is the second most frequently measured parameter in liquid media. pH sensors on an electrochemical measuring principle always consist of two electrodes, namely the ph-sensitive electrode and the reference electrode. The reference electrode on a multiparametric sensor can also be used for other electrochemical sensors (ion-selective sensors).
The fields of application are manifold. From bioreactors, wound monitoring on patients to drinking water monitoring. Measure at positions and in an economical way where glass electrodes or ISFET cannot reach.
