Abstract:

The present paper describes an electrochemical device for measuring oxygen which is basically a simple polarographic unit, but has certain details and characteristics which it may be worthwhile to report. The device was designed primarily to measure oxygen in gases rather than in liquids, and this design has allowed applications under many adverse field conditions over relatively long periods of time. Essentially, the design involves the use of suitable electrodes placed in an insulated electrode housing. An electrolyte is added and a gas-permeable membrane applied in such a manner as to encapsulate the electrodes and fluid after suitable degassing procedures have been carried out. An additional feature is a protective cover which holds the membrane in place and prevents it displacement or rupture through rough handling.
