- Abstract:
- The triple point of mercury is one of the defining fixed-points of the International Temperature Scale of 1990 (ITS-90). Its value was assigned to be 231.3456 K (-38.8344°C) by ITS-90 and has an unique importance since it is the only fixed-point suggested by ITS-90 between 0.01°C and -190°C. Four mercury cells from borosilicate-glass were constructed at TUBITAK-UME Temperature laboratory. The details of construction phase then the measurement and comparison results with the reference UME cell will be given in this paper.
