Product Description
752N UV-vis Spectrophotometer is an necessary instrument in each laboratory. And it's the most popular model for the cheap price and good performance.


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.
