Abstract

Developed new technology of heat procedure for preparation pure structure of platinum wire, which produce stable resistance coefficient, stable crystalline structure sturdy against contamination of inpurities. By this technology we produce Primary Standard Platinum Resistance thermometer what present high sable resistance thermometer with stability level &plusmn;2 to 3 &times; 10^-4 K what is stability level of water triple point cells 273.16 &plusmn; 2 to 3 &times; 10^-4 K, testing device in laboratory.<BR />This publication is based on work sponsored by the U.S.-Slovak Science and Technology Joint Fund in cooperation with Agency for International Scientific and Technological Cooperation under Project Number 93 016.
