The design and performance of potentiometric multisensor system made in solid‐contact technology is described. Both, the measuring electrodes as well as the reference electrode are in a compact cell. The system allows for simultaneous measurement of various ions. The characteristics of the electrodes for Na + , K + and Ca 2+ ions were determined using the designed system and compared with ISEs of the same membrane composition in classical system. The potentiometric cells were used to determine the concentration of the ions in synthetic and real human sweat samples. The obtained results for synthetic samples were compared to the expected values and for collected real sample of sweat were compared to the results obtained by flame photometry (Na + , K + ) and by AAS (Ca 2+ ).
