Description
Product Introduction
The Triple Point of Water (TPW) is a temperature fixed point defined by both the thermodynamic temperature scale and the International Temperature Scale. The unit of thermodynamic temperature, Kelvin, is defined as the thermodynamic temperature of the triple point of water 1/273.16. It is also a defined fixed point for the International Temperature Scale of 1990 (ITS-90). Therefore the triple point of water temperature is an important, accurate, and easy-to-use temperature standard. The triple point of water cell achieves 0.01°C temperature with an expanded uncertainty of less than 0.0001°C.
