Uses:

721/722 Series visible Spectrophotometer widely used in the factories, Mine, Health, School, Environmental protection, scientific research and Laboratories. Our aim is to provide our customers the precision analysis instruments.

721Characteristics:

1. Use the new model rays design and the new model 1200/mm raster display make sure the low stray light and good monochromatic light.
2. Adopting the SCM, adjust the 0%T and 100%T so easy.
3. Two kinds measure method, T and A make the operation more easy.
4.31/2LCD screen, big sample chamber can expand the apparatus function.
5.721-100 model with 100mm cell rack, more suitable for water analysis and sample content analysis in Water works and generating station.
