Specifications
Visible spectrophotometer721G/722G Visible spectrophotometer
Basic theory
Substance of different molecular structure differ in the selective absorption of electromagnetic radiation, Spectrophotometer analysis method is based on this.
We regarded application of electromagnetic radiation spectrum area which ranges from 330nm to 800nm as visible spectrophotometer.
Application
It adopts microprocessor control technology and does qualitative and quantitative analysis in the visible spectrum. This is a necessary multifunctional analysis instruments in Routine laboratory . It can be used in the Medical, clinical examination, biological chemistry, petrochemical, environmental protection, quality control and the departments of teaching Laboratory in college.
Characteristics
- With LCD backlight type screens, reading clarity.
- Adopt advanced monochromator in the C-T style of holographic glaring optical grating. It has the advantages of high wavelength accuracy, good monochromaticity, low stray light.
- Adopt PC measurement system, high wavelength accuracy of C-T,It can adjust automatically in 0% and 100%, reading concentration directly, setting concentration factor,and can carry out data printing function by choosing serial data printers.
- Measurement reading is very accurate, reproducible and stable.
- Printer can be equipped by your choose.
Main Technical Parameters
