Brief introduction of CX-NS-120 oxygen electrode
NS-120 type oxygen electrode is a diaphragm polarographic (clark) sensor . Byconductibility electrolyte which connect one cathode and one anode to compose .Between the cathode and the anode ,the proper polarization voltage can deoxidize the O2 at the Cathode electrode .
Cathode reaction:O2+ 2H2O +4e → 4OH-
Anode reaction ::4Ag +4Cl- → 4AgCl + 4e
These chemical reactions produce the current which is proportional to the O2 in the measured solution's
