   Product Description    Specifications
 
The Isothermal range of Thermocouple Standards are the result of many years of development. The type R and S standards cover the range from 0°C to 1600°C.

The measuring assembly is comprised of a 7mm x 300mm or 600mm gas tight 99.7% recrystallized alumina sheath, inside which is a 2.5mm diameter twin-bore tube holding the thermocouple.

The covered noble metal thermocouple wire connects the measuring sheath to the reference sheath, which is a 4.5mm x 150mm stainless steel sheath suitable for referencing in a 0°C reference system. Two thermoelectrically free multistrand copper wires (teflon-coated) connect the thermocouple to the voltage measuring device.

The thermocouple material is continuous from the hot, or measuring junction to the cold, or referencing junction.

ISO-17025 Accredited Calibration Included
The 1600 comes with a certificate giving the error between the ideal value and the actual emf of the thermocouple at the gold point. For types R and S thermocouples, manufacturing tolerances are small and, therefore, the use of a standard reference table is particularly apt. Only a few calibration points are required to determine the small differences between the characteristics of an individual thermocouple and the standard reference table. As an example of consistency, 48 Isotech thermocouples calibrated at NPL had a standard deviation of the differences from the reference table value at the gold point (11, 364V) of only 7V, equivalent to about 0.5°C. Thermocouple characteristics are smooth enough to allow interpolation of deviations from the reference table to be carried out over fairly wide temperature spans without introducing unacceptable errors.

The standard thermocouple described can be supplied in the following noble metal combinations:
TYPE R: Platinum vs Platinum 13% Rhodium
TYPE S: Platinum vs Platinum 10% Rhodium

If cold junction is not required, specify NCJ.
UKAS calibration is included
