Dielectric barrier discharge (DBD) plasma jet with constant He flow of 1000 SCCM, operating at applied voltage of 2 kV and 30 kHz, was positioned above the liquid surface. Electric field measurement was performed using Stark polarization spectroscopy when Petri dish with distilled water or physiological saline (0.85 % NaCl) was positioned 10 mm below the plasma jet nozzle. Obtained axial distributions of the electric field show that maximal values of the field are similar for different targets
