Characteristics
The monochromator with a holographic flashing  grating is used. It has the advantage of high  wavelength precision, good monochromaticity and  low stray light.
Automatic switching of tungsten halogen lamp and  deuterium lamp.
A sample compartment for 0.5cm-5cm cells.
Computer control system, precise automatic T/A  changeover.
Automatic zero and full scale adjustment.
Direct concentration read-out and concentration  factor setting function.
Equipped with RS232 port. Printer can be  connected and data can be sent to PC by special  software.
