<p>PURPOSE:To prevent a temperature recording unit form being damaged caused by high or low temperature, shorten a time taken for reuse and enable a temperature measuring equipment to be quickly reused. CONSTITUTION:A temperature recording unit 3 is accomodated in a heat insulating receptacle 1 of a stainless steel made double structure 2 the inside of which is evacuated. A temperature sensor 7 connected electrically to the temperature recording unit 3 is located in any measuring position outside the insulating receptacle 1 to close an entrance part 4 with a heat insulating plug 5 and fixture 9 made of a heat resistive resin. The heat insulating plug 5 is formed of a bag 5D of heat resistive fibers enveloping a glass wool heat insulating material outer layer 5A outside the heat insulating receptacle 1, a glass wool heat insulating material inner layer 5C inside the heat insulating receptacle and a heat accumulating material layer 5B of a stainless steel plate between both layers. A copper made heat transmitting member 8 continued to the heat accumulating material layer 5B is pressed against the inner wall of a double structure 2. After the measurement, the temperature recording unit 3 is taken out, and the separated double structure 2 and the heat accumulating material layer 5B can be quickly restored to the room temperature.</p> |
