Hart Scientific has developed a new generation of fixed points for secondary and field applications, which do not require accompanying heating or cooling apparatus to achieve their realization. Three fixed points have been tested, including the melting point of gallium (29.7646°C), the triple point of diphenyl ether (26.864°C), and the melting point of a gallium/8% tin eutectic alloy (20.476°C). The only thermal source needed to realize melting curves lasting a few hours is the warmth of a person’s hand.
