721GVisible spectrophotometer (classic)

Application range.

The use of microprocessor control technology to make qualitative and quantitative analysis of substances in the visible spectrum region is a necessary multi-purpose analytical instrument in conventional laboratory. it is used in medical and health, clinical testing, biochemistry, petrochemical, environmental protection, quality control and teaching laboratories in colleges and universities.



Product introduction.
Features:
With backlit LCD display screen, the reading is clear.
The holographic blazed grating Cmurt Monochromator is adopted, which has the advantages of high wavelength precision, good monochromaticity and low stray light.
Using microcomputer measurement system, TMel A conversion accuracy is high, and it can automatically adjust 0% (T) and 100% (T), concentration direct reading, concentration factor setting, and can choose serial data printer for data printing.
The measurement has high accuracy, reproducibility and stability.
Optional printer.
Basic principles:
Spectrophotometer analysis is based on the selective absorption of electromagnetic radiation by substances with different molecular structures.
The spectral region of electromagnetic radiation is usually used as a visible spectrophotometer in 330nm~800nm.
Main technical indicators:
Wavelength range: 340nm~1000nm (721G) 325nm~1000nm (722G).
Wavelength accuracy: ±2nm.
Wavelength repeatability: ≤ 1nm.
Accuracy of transmittance: ±0.5 (T).
Renaturation of specific gravity of transmission: ≤ 0.2% (T).
Spectral bandwidth: 5nm.
Stray light: ≤ 0.5% (T) (at 360nm, measured by NaNO2)
