<p>1350793 Electro-chemical analysis ALLMANNA SVENSKA ELEKTRISKA A B 26 Aug 1971 [27 Aug 1970] 40069/71 Heading G1N In a system for determining oxygen in molten metal using an expendable, plug-in, solidelectrolyte probe, a pre-amplifier is mounted in the head of the lance. A probe construction is shown with a solid electrolyte plug 20 in a silica tube; counter electrode 9; thermo-element 11, and plug in contacts 15, 16, 17. The silica tube holds sufficient air for an oxygen reference during measurement, and a "throttle" 19 allows for expansion.</p> |
