Intercomparison of zinc freezing point cells and standard platinum resistance thermometers
Abstract
Four standard platinum resistance thermometers (SPRTs) and four zinc freezing point cells were compared. Pronounced differences are found between the SPRTs but no differences are found between the cells. Interaction between cells and SPRTs in two instances is indicated. It is found that one interaction is spurious because of an anomalous data point. No grounds are found for discounting the validity of the second interaction.
