- Model 721G UV-VIS Spectrophotometer
-
Specifications of Model 721G UV-VIS Spectrophotometer:
1. Features:
1). The monochromator with a holographic flashing grating is used. It has the advantage of high wavelength precision, good monochromaticity and low stray light.
2). Automatic switching of halogen lamp and deuterium lamp.
3). A sample compartment for 0.5cm~10cm cells.
4). Computer control system, precise automatic T/A changeover.
5). Automatic zero and full scale adjustment.
6). Direct concentration read-out and concentration factor setting function.
7). Equipped with RS232 port. Printer can be connected and data can be sent to PC by special software.2. Technical information:
