GD-752N Ultraviolet Visible Spectrophotometer
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
