由南京仙林电子仪器厂生产的SGF-I型、IA型和SWGY—Ⅰ、Ⅱ型仪是在STGY和SZGY仪基础上研制而成,经组织专家鉴定:一致确认仪器分辨率高(±0.1HRC、±1HB)、精度高(误差HRC≤±1、HB≤±10)、重复性好,且稳定可靠.与同类产品比较,居国内领先地位,达到了国际先进水平.现在南京仙林电子仪器厂与有关的高等院校结合,使用更优质的电子元件,线路进一步数字化和集成化,因而使整机性能更加稳定,测量更精确,数据用数字显示更加直观,并更经久耐用.
The SGF-I, IA and SWGY-I, II instruments manufactured by Nanjing Xianlin Electronic Instrument Factory were developed on the basis of STGY and SZGY instruments and were certified by the experts in the tissue. Consistently confirm the high resolution of the instrument (± 0.1 HRC, ± 1HB), high precision (error HRC ≤ ± 1, HB ≤ ± 10), repeatability, and stable and reliable. Compared with similar products, ranking the leading domestic and reached the international advanced level. Now Nanjing Xianlin Electronics Instrument factory and the relevant institutions of higher learning, the use of higher quality electronic components, further digital lines and integration, thus making the machine more stable performance, more accurate measurements, digital data display more intuitive and more durable.
