ISTANDARD PLATINUM RESISTANCE THERMOMETERS ISTANDARD PLATINUM-COBALT RESISTANCE THERMOMETER These are standard temperature sensors conforming to the International Temperature Scale of 1990. The temperature range from 4 K to 962 °C is measured by there sensors which are classified into a standard platinum-cobalt resistance thermometer for cryogenic temperature, standard platinum resistance themometers for low temperature, medium temperature and high temperature. The R800 series standard platinum resistance thermometers, which have been commercialized under the guidance of the NMIJ, have been adopted by national metorology institute in overseas countries with reputation on their performance and reliability. •These sensors are manufactured with selected quality materials by highly skilled manufacturing techniques under •The standard platinum resistance thermometer for low temperature is the first international product in Japan as the standard thermometer applicable to 13 K. •The standard platinum resistance thermometers for medium temperature and for high temperature have been delivered to national measurement institute in overseas countries in large quantities. Its performance has been highly reputed in Comite Consultatif de Thermometrie (CCT). •The standard platinum-cobalt resistance thermometer for cryogenic temperature features excellent reproducibility and stability in a cryogenic temperature range below to 4 K.
