可见分光光度计计量校准 产品简介
721G型可见分光光度计 技术参数:
■ 波长范围:340nm~1000nm(721G,721G-100) 325nm~1000nm(722G)
■ 波长准确度:±2nm
■ 波长重复性:≤1nm
■ 透射比准确度:±0.5%(T)
■ 透射比重复性:≤0.2%(T)
■ 光谱带宽:5nm
■ 杂散光:≤0.5%(T)(在360nm处,以NaNO2测定)
721G型可见分光光度计 性能特点:
■ 具有背光式LCD显示屏,读数清晰明暸。
■ 采用先进的全息闪耀光栅C-T式单色器,具有波长精度高,单色性好,杂散光低等优点。
■ 采用微机测量系统,T-A转换精度高,并有自动调整0%(T)和调整100%(T),浓度直读、浓度因子设定,并可选择串行数据打印机进行数据打印功能。
■ 测量读数准确性高,重现性和稳定性佳。
■ 可选配打印机。
721G型可见分光光度计 工作原理:
■ 分光光度计分析法是基于不同分子结构的物质对电磁辐射选择性吸收而建立的分析方法。
■ 应用电磁辐射波谱区通常在330nm~800nm为可见分光光度计。
公司介绍:
Hebei Huajian Metrology & Testing Co. , Ltd. was established in 2017, the company in July 2017 according to CNAS-CL01:2006“Testing and calibration laboratory accreditation criteria”; The quality management system has been established and operated by CNAS-CL25 and CNAS-CL52 standards such as the application specification of the accreditation criteria for testing and calibration laboratories in the field of calibration According to the JJF1033 examination standard, the measurement standard is prepared, and the uncertainty evaluation, stability and repeatability examination are carried out for all the verification/calibration projects. Through the length, temperature, mechanics, construction, traffic measurement equipment, chemical and other fields of a number of measurement standards. Through the China National Accreditation Service for conformity assessment (CNAS) accreditation, certificate number: CNAS L11171. Can carry out the length, thermodynamics, mechanics, construction, traffic special measuring instruments, chemistry and hundreds of other calibration projects.
