The Water Triple Point is the most important fixed point, the only point common to the ITS-90 and the Thermodynamic Temperature Scale. It is an essential reference point for every temperature laboratory. The Jarrett-Isotech cells are the best standard, all cells are not the same, accept no inferior device.

Total Confidence – The Internationally Proven Cells The Jarrett-Isotech cells have been in production since 1958. A independent comparison* in 1981 showed the first cell to be within 0.000006°C of the reference cell. The most recent international study organized by BIPM** consistently shows labs using both recent and older Jarrett-Isotech cells tightly grouped, tens of μK around the BIPM reference value.

International comparisons prove the quality of the Jarrett-Isotech Cells and are unique in the number, and history of comprehensive evaluations.
