Oxygen measurement in liquids - using gold and antimony alloy electrodes having equal abrasion rates

Oxygen measurement in liquids - using gold and antimony alloy electrodes having equal abrasion rates

An oxygen-content determination device for liquids, e.g. effluent or sludges, comprises an electrode unit with a revolving wiper, the cathode is of Au and the anode of Pb-Sb (30-40% Sb) having the same abrasion resistance as the Au. The prefd. arrangement comprises tubular electrodes, the outer one...

Zusammenfassung:An oxygen-content determination device for liquids, e.g. effluent or sludges, comprises an electrode unit with a revolving wiper, the cathode is of Au and the anode of Pb-Sb (30-40% Sb) having the same abrasion resistance as the Au. The prefd. arrangement comprises tubular electrodes, the outer one being the anode. Pref. both electrodes are embedded in a plastics block, surrounded by a protective bowl.
