检测范围为 5× 10 5～ 1× 10 -2 Ｐａ,不确定度为 0 .0 2 %～ 5 %的全金属静态膨胀法真空标准装置在上海市计量测试技术研究院建成 ,并于 1月 2 3日通过上海市质量技术监督局验收。该真空标准装置的整体水平已跃居国内领先地位 ,不久亦将成为华东地区最高社会公用计量标准装?
The whole metal static expansion method vacuum standard device with the detection range of 5 × 10 5 ~ 1 × 10 -2 Pa and the uncertainty of 0.2% ~ 5% was built in Shanghai Institute of Metrology Technology and in January 2 3 through the Shanghai Quality and Technical Supervision acceptance. The overall level of the vacuum standard device has leapt to the domestic leading position in the near future will also become the highest social and public standard measurement equipment installed in East China?
