Triple Point of Water Cells calibrate/verify thermometers.

Offering uncertainties of better than ±0.0001°C, cells contain distilled ocean water with isotopic composition nearly identical to international standard Vienna Standard Mean Ocean Water (VSMOW). Errors associated with poor isotopic composition can be as large as 0.00025°C (0.25mK), and uncertainty contribution from VSMOW errors is less than ±0.000007°C (7Â-µK)....
