Provided is a cryogenic temperature measuring resistor element including a metallic temperature measuring resistor wire, an electric insulator made of a polycrystalline ceramic material, and a filler filled between the electric insulator and the temperature measuring resistor wire. The filler includes polycrystalline inorganic electric insulating powder, particles of the insulating powder being connected by glass. The glass has a lower softening point than respective melting points of the inorganic electric insulating powder, the temperature measuring resistor wire, and the electric insulator.

Using a small-type crucible, the inter-laboratory comparison of the realization of the Co-C eutectic point was executed in the industrial field in Japan, with the aim to verify the possibility of thermocouple calibration at the eutectic point with an existing furnace of not so good temperature distribution: the palladium-point wire-bridge method furnace for thermocouple calibration. A small-type crucible for thermocouples was made by the National Metrology Institute of Japan, National Institute of Advanced Industrial Science and Technology (NMIJ/AIST). The inter-laboratory comparison was piloted by the Tokyo Metropolitan Industrial Technology Research Institute (TIRI), a public test and research organization in Tokyo, and was conducted among five calibration laboratories including the pilot. One of the five laboratories is a designated calibration laboratory in Japan, and the three remainders are private laboratories. Four laboratories including TIRI used existing palladium-point furnace, and one laboratory made a new furnace for this inter-laboratory comparison. © 2012 The Institute of Electrical Engineers of Japan.
