Name: Visible spectrophotometer
Model: 721G
1. Basic principle:
1. Spectrophotometric analysis method is based on substances of different molecular structure analysis methods established by selective absorption of electromagnetic radiation.
2. The application of electromagnetic radiation spectrum zone typically 330 nm to 800 nm visible spectrophotometer meter.
2. Application:
The microprocessor control technology, qualitative material in the visible spectral region, quantitative analysis, routine laboratory essential multi-purpose analytical instruments used in health, clinical examination, biochemical, petrochemical, environmental protection, quality control and tertiary institutions teaching laboratories and other departments.

3. Features:
1. Backlit LCD display, reading clarity.
2. The use of advanced holographic blazed grating CT-type monochromator, with a high wavelength accuracy, good color, low stray light.
3. Computer measurement system, TA conversion accuracy, and automatically adjust the 0% (T) and adjustment of 100% (T), concentration direct reading concentration factor set, and can select a serial data printer for data printing capabilities.
4. Readings high accuracy, good reproducibility and stability.
5. Optional printer.
6. UVWin7 package (optional).
