The basic principle:
The spectrophotometric analysis method is established and the analysis method of different molecular structure of the material based on the selective absorption of electromagnetic radiation.
The application of electromagnetic radiation spectrum is usually in the 360nm ~ 1000nm visible spectrophotometer.
Characteristic：
- microprocessor control technology, analysis to qualitative and material in the UV visible spectral region is quantitative, multi-purpose routine laboratory analysis instruments necessary.
Adopt the advanced holographic blazed grating monochromator wavelength, has high precision, good monochromaticity, low stray light.
Super large screen backlit LCD display, the measurement data at a table.
Adopt the computer measurement system, T-A conversion precision, and automatic adjustment of 0%T and 100%T, the concentration factor setting, direct reading.
The measurement of high accuracy, good reproducibility and stability.
- optional serial printer and software with the use of UVWin7, expand the instrument function.
The UVWin7 software package (optional).
