Vis-7220G & UV-9200
The VIS-7220G & UV-9200 are intelligent UV/Visible spectrophotometers that are well suited to the qualitative and quantitative analyses required by today's laboratories. With its wide wavelength range and narrow bandwidth, the instrument provides extraordinary flexibility and high resolution at an exceptional price.
They come with the following features and specifications:
- Microprocessor control, 16x2 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 (USB port).
- PC control provided for more accurate and flexible measurement requirements (optional).
The only difference between the VIS-7220G & UV-9200 is the wavelength which is 320∼1100nm (visible range) for the VIS-7220G while it is 190∼1100nm in the UV-9200.
