Dissolved oxygen electrode

·Application

It is widely use in the applications like water treatment , hydrological monitoring , wastewater treatment ,swimming pools fish ponds and fertilizer .

Chemical ,biological and other fields about the oxygen content monitor .

·Measuring principle

N S-120 type oxygen electrode is a diaphragm polarographic (clark) sensor . By conductibility 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 partial pressure .

·Feature

Sensitive response ,good stability

Do not need to replace the diaphragm and the electrolyte .

Suitable for variety of waste water , the diaphragm is difficult to be damaged, anti-pollution .

·Technical parameters

Measuring principle :current measurement/polarography

Detection limit <40ppb oxygen percent

Response time :the oxygen content decreased 90%<2min ,when the temperature is 25 Celsius degree Residual current :the residual room temperature signal<2% FS in the anaerobic medium
