This report describes the design and intended use of a constant pressure and vacuum transporter for transferring 1 kg mass standards between different locations and environments without compromising the atmospheric conditions and therefore maintaining stability of the surface and mass values of the artifacts. The development of this transporter is intended for transferring 1 kg artifacts between a vacuum mass comparator and the NIST Watt balance.
