The high and low concentration of the sample can be accurately measured by the PMT of high sensitivity. The PM tube is applied with the high voltage which is controlled and the wider range of dynamic is allowed by dynode feedback circuit. The usage of the accessories of solid sample handling is also enabled by the product as integrating spheres for the collection of diffuse light reflected and transmitted by the sample. The high optical throughput is provided by the latest optical design of the product. The work of high resolution likes vapor and gas phase spectroscopy is allowed by the product with the setting of bandwidth 0.1 nm low. Outstanding linearity is provided to absorbance units up to 4 which is enabled by the setting of low stray light slit. The device offers two user interface of graphical with intelligent remote module which is re designed. It also includes the Spectra Manager™ II software which is the updated version of cross-platform spectroscopy software. Advanced processing of data and control of full system is enabled by the both interfaces.
