testing instrument
752N Single Beam 200nm to 1000nm UV VIS Spectrophotometer
Features:
1. The mon℃hromator with a holographic flashing grating is used. It has the advantage of high wavelength precision, good mon℃hromaticity and low stray light.
2. Automatic switching of tungsten halogen lamp and deuterium lamp.
3. A sample compartment for 0.5cm-5cm 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.
