Main features:
1. L7 Double Beam UV-VIS Spectrophotometer adopt double beam optical system and blazed holographic gratings, it has outstanding test precision and very competitive price.
2. 8-inch color touch screen, cutting-edge user interface, powerful functions and easy operation.
3. With powerful functions, the instrument shows great performance in qualitative and quantitative testing, such as:
* Full-spectrum scanning
* Linear regression
* Detailed spectrum scanning
* Concentration direct reading
* Time based kinetics determination
* Peak/Valley detecting
* GOTOλ
* Multi-wavelength measurement
4. The instrument is designed with sophiscticated power protection system, with high capacity of internal memory, it stores testing results, scanned images, regression equations and correction data, therefore, it follows a fast initialization when power on.
5. The instrument can be connected with dedicated printer to output testing results or draw curve from spectral scanning, fixed wavelength time based scanning and linear regression.
6. With USB Interface the instrument can be connected to PC, which not only enhances the performance in data testing and spectrum scanning, but also expands the memory to save more testing results.
