2200r series quasi double beam spectrophotometer is practical and easy to operate. The main machine of the instrument is equipped with lattice LCD, which can be used for photometric measurement and quantitative test, and the standard curve graph is displayed directly. It is more convenient to operate online by selecting PC scanning and analysis software, and it also increases the functions of wavelength scanning, time scanning, data processing and report printing, and expands the data storage capacity. It is widely used in teaching and daily analysis.
