Abstract:

Automatic apparatus for measurements of autoxidation at constant oxygen pressures normally relies on the make and break of mercury contacts. These are usually troublesome because of their sensitivity to small temperature changes and to contamination. These problems, as well as those connected with contacts in which a liquid meniscus can vary in shape, were successfully overcome with the aid of a stainless steel float and the elimination of the mercury itself, viz the electrical contact maker.
