Product Description
L7 Double Beam UV-Vis Spectrophotometer
1 double beam optical system
2 8-inch color touch-screen
3 automatic zero and full scale adjustment
4 automatic wavelength settings
5 equipped with USD COM port
6 UV WIN8 spectrum data processing software optional
7 thermal plotter optional
Features
1 L7 double beam UV-VIS spectrophotometers adopt double beam optical system, and blazed holographic gratings. They have outstanding test precision and very competitive prices.
2 8-inch color touch-screen, cutting edge user interface, powerful functions and easy operation.
3 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
4 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.
5 the instrument can be connected with dedicated printer, which can print testing results, or draw curve from spectral scanning, fixed wavelength time-base scanning, and linear regression.
6 with USB COM port 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.
