    SP-1920 Dual Beam UV-Vis Spectrophotometer
    Introduction
    The SP-1920 dual-beam UV-Vis spectrophotometer uses spatially split dual-beam, asymmetric vertical measurement optical path technology (patented technology). Compared with the traditional two-beam technology, the structure of the instrument is simplified and the reliability is greatly improved due to the simple optical path. 
    Features
    Plug-in light source design, no special tools required for replacement, no optical path calibration, easy operation
    Large-capacity sample room with a variety of special accessories to meet different measurement requirements
    Modified optical components, high sensitivity photodetectors, high performance A/D devices, etc.
    The self-developed software workstation system has powerful data processing and graphic capabilities, and is equipped with an audit trail function to meet the analysis requirements of samples in various industries.
