DEVICE FOR DETERMINATION OF STABILITY OF LOW-TEMPERATURE THERMOMETERS

摘要

Device for determination of stability of low temperature thermometers includes a cylindrical block for temperature leveling made of oxygen –free copper, with equidistant from the center of the block cylindrical openings with reference resistance thermometer and thermometers stability of which is determined placed there, electrical lone of connection of thermometers connected through electric connector to secondary apparatuses. In the openings of the temperature leveling block one additionally places by means of threaded joint cylindrical holders made of oxygen –free copper, those have through rectangular cuts and spring clips for installation of thermometers stability of which is determined.
