With its wide wavelength range and narrow bandwidth, the instrument provides extraordinary flexibility and high resolution at an exceptional price.

The Vis-7220G and UV-9200 come with the following features:

• Microprocessor control, 16 x 2 LCD display.
• Auto zero and auto 100% T adjustment provided.
• calibration curve can be set up by either measuring or entering up to 10 standards or entering K and B factors directly via the keyboard.
• parameters can be saved for later use. Up to 10 calibration curves can be stored and edited for user's convenience.
• Data can be printed on an optional desktop printer and can be downloaded to a PC through RS-232.
• PC control provided for more accurate and flexible measurement requirements (optional).

The only difference between the Vis-7220G and UV-9200 is the wavelength which is used in the visible area fot the Vis-7220G while it is used in the ultraviolet area for the UV-9200.
