QuantumPascal Report D8 Report on the circular comparison between a transportable Fabry-Pérot refractometer and the conventional primary standards that are available at different facilities, including conclusions about how the refractometric method and the optical refractometer should be handled outside of well controlled laboratories in order to enable and simplify future adaptations by end users

Description

This report summarize the circular comparison of pressure balances using a transportable Fabry-Perot refractometer developed within 18SIB04 QuantumPascal. The report shortly describe the transportable system and how it operates. Thereafter, details about each measurement together with the results showing that transportable refractometer is capable of performing a full circle comparison that can demonstrate that the pressure balances agrees well within their uncertainties. Finally, some general conclusion and recommendation on how a transportable refractometer can be improved in terms of both performance and simplicity for future use.
