721/722 Series Visible Spectrophotometer
Product Description
Feature
721 series
1.Use the new model rays design and the new model 1200/mm raster display make sure the stray light los and monochromatic light good.
2. Adopting the SCM,adjust the 0% T and 100% T so esily.
3.Two kinds of measure methods,T and A make the operation easier.
722 series
1. Use the new model rays design and the new model 1200/mm raster display make sure the stray light low and monochromatic light good.
2. Adopting the SCM,adjust the 0% T and 100% T so easily.
3. Four kingd of measure methods,T,A,C,F,make the operation easier.
4. Slope(F)measure method needn’t do the standard sample for each measure.
5. Φ8-22mm cell rack (single chamber).
6. l Option:RS-232 connects with computer can realize two-way communication.
