REALIZATION OF THE ITS-90 FOR RANGE 232 °C – 962 °C ON KE LP4 AT METROLOGY-LIPI
Hidayat Wiriadinata, Iip Ahmad Rifai, Aditya Achmadi, Arfan Sindhu Tistomo
Abstract:
The realization of ITS-90 has been done at Metrology-LIPI using the radiation thermometer monochromatic KE LP4 80-59 over a temperature range 232 - 962 ° C and wavelength λ = 1.57 µm. The method used is Sakuma-Hattori method using fixed-point blackbody tin, aluminum and silver. The value of the uncertainty of the KE LP4 80-59 at the temperature range for the level of confidence of 95% and a coverage factor of k = 2, is expressed by the equation: U(t) = 1.067461375 - 0,008000541 · t + 2,586471 · 10-5 · t2 -3,33928 · 10-8 · t3 + 1,497270 · 10-12 · t4.
