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. Technical Parameters
