随着我国测温元件技术的不断发展,对于检定装置提出了更高的要求,迫切需要一种能够在0℃～210℃的温区适合定期、成批检定要求的装置,以代替目前使用的酒精槽式的、温度下限只能达到-100℃的检定装置。在伟大领袖毛主席“自力更生,艰苦奋斗,破除迷信,解放思想”的方针指引下,旅大市计量标准处,天津市计量管理所与大连第四仪表厂,天津华北电器厂和大连光明化工研究
With the continuous development of temperature measurement element technology in our country, higher requirements are put forward for the verification device, and a device capable of being suitable for periodic and batch verification requirements in a temperature range of 0 ° C ~ 210 ° C is urgently needed to replace the currently used Alcohol tank type, the temperature limit can only reach -100 ℃ of the test device. Under the guidance of Chairman Mao, the great leader, “self-reliance, hard work, superseding superstition and emancipating the mind”, the measurement standards department of Luda City, Tianjin Metrology Administration and Dalian No.4 Dashboard Factory, Tianjin North China Electric Appliance Factory and Dalian Guangming Chemical Research
