Common features
1. The L series of spectrophotometers adopt split beam survey optical system, and blazed holographic gratings. They have outstanding test precision and very competitive prices.
2. 8-inch color touch screen LCD display, cutting-edge user interface, powerful functions, and easy operation.
3. The automated eight-position cuvettes holder facilitates the operation under each measurement mode.
4. With powerful functions, the equipment shows great performance in qualitative and quantitative testing, such as:
Full-spectrum scanning
Detailed spectrum scanning
Time-based kinetics determination
GOTO λ
Linear regression
Concentration direct reading
Peak/Valley detecting
Multi-wavelength measurement
5. The equipment is designed with sophisticated power protection system. With high capacity of internal memory, it can store testing results, scanned images, regression equations and correction data. Therefore, it follows a fast initialization when power on.
6. The instrument can be connected with dedicated printer, which can print testing results, or draw curve from spectral scanning, fixed wavelength time-based scanning, and linear regression.
7. There is a USB port on the device, and UVwin8 software is optional to order. The device can be connected to a PC, which can not only enhance the performance in data testing and spectrum scanning, but also expand the memory to save more testing results.
