It has been shown that a cell for realising either the triple or the melting point of gallium is a very reproducible fixed point device near 29.77 C. Potentially, it has several important applications as a secondary reference point in, for example, the calibration of standard platinum resistance thermometers, and in the checking of medical thermometers. However, to establish its validity as a fixed point, its reproducibility when manufactured to different designs and with gallium from different sources, needs to be determined. The work described in this report concerns the characterisation of gallium cells manufactured by three national standards laboratories. Each laboratory manufactured its own cell using a slightly different design and a different source or purity of gallium.
