Product Introduction

    The DY-DP Water Triple-Point Bottle (TPW) is a fixed temperature point defined both by the thermodynamic temperature scale and the international temperature scale. The unit of thermodynamic temperature, Kelvin, is defined as 1/273.16 of the thermodynamic temperature of the water triple point. It is also a defined fixed point in the International Temperature Scale of 1990 (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°C with an expanded uncertainty of less than 0.0001°C.
