◇ Product Introduction ◇ Product Features◇ Technical Indicator

[Product Introduction]

DY-DP Water Triple Point Flask (TPW) is a temperature fixed point defined by both thermodynamic and international temperature scales.

The unit of thermodynamic temperature, Kelvin, is defined as the water triple point thermodynamic temperature 1/273.16. It is also the fixed point for the definition of the 1990 International Temperature Scale (ITS-90).

Therefore, the water triple point temperature is an important, accurate and easy to use temperature standard. The water triple point bottle achieves a temperature of 0.01℃ with an extended uncertainty of less than 0.0001℃.
