Our product experts are here to help you find the right solution for your application!

Fluke Calibration scientists have designed and tested ITS-90 fixed-point cells for many years. Not only do we manufacture all the major fixed points, our metrologists have written extensively on the theory and use of cells and have created new designs covering a range of applications no other company can match. Our testing of fixed-point cells is also unmatched. The scope of our accreditation includes the testing of ITS-90 fixed-point cells. Each cell may be purchased with this intercomparison option, which includes comparing the equilibrium value of your cell against that of a reference cell.

• Best cell uncertainties commercially available
• Every ITS-90 fixed point available from argon to copper
• Plateaus last days (gallium for weeks and TPW for months)
• Manufactured and tested by Fluke Calibration’s primary standards scientists
