Why the Jarrett-Isotech Cell is the best standard?
The Jarrett-Isotech range of Water Triple Point Cells is unique. Unique in being in production for over 45 years. Unique in having 12 steps in the water purification process.
Unique in having the most comprehensive evaluations ever made on Water Triple Point Cells performed on it.
One assumes that every Water Triple Point Cell, no matter from which source will be the same. This is not so. Each manufacturer employs his own design of distillation plant to produce the pure water that goes into the Cell, and cleans the Cell in different ways.
The Jarrett Instrument Company and in particular its proprietor James L. Cross devoted 45 years with no other product in his range, to the understanding and perfection of the Water Triple Point Cell.
As improvements became possible, or research showed that additional precautions were necessary, additional steps were placed in the distilla cells as close to ITS-90 as possible.
