Product Description

Product Overview

The water triple point bottle is the only 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 water triple point.
It is 1/273.16 of thermodynamic temperature. It is also the defined fixed point of the 1990 International Temperature Scale (ITS-90). Therefore, the water triple point temperature is the most important, accurate, and easy-to-use temperature standard.
The water triple point is reproduced using a water triple point bottle. The bottle contains high-purity water, with isotopic composition equivalent to seawater. If you
have a standard platinum resistance thermometer, you must have a high-quality water triple point bottle. Our company's water triple point
bottle has extremely high purity and very low uncertainty, achieving a temperature of 0.01℃ with an expanded uncertainty of less than 0.0001℃.
The water triple point bottle must be frozen to the triple point using dry ice or liquid nitrogen, and then stored in an ice bath composed of crushed ice and water.
Alternatively, you can use our company's NM-03 water triple point bottle automatic freezing and storage device to automatically achieve the freezing and storage of the water triple point bottle.

Technical Parameters
★ Water triple point bottle dimensions: Φ60×380 (mm)
★ Water triple point bottle trap hole diameter: Φ12mm
★ Water triple point bottle reproducibility: ≤ 0.1mK
