Product Description
Lab high-precision 190-1100nm uv/vis spectrophotometer for food medicine health agricultur
L7 double beam UV-VIS spectrophotometers adopt double beam optical system,
and blazed holographic gratings.
Product Details：
L7 double beam UV-VIS spectrophotometers adopt double beam optical system, and blazed holographic gratings.
They have outstanding test precision and very competitive prices. 8-inch color touch-screen, cutting-edge user interface, powerful functions, and easy operation.
With powerful functions, the equipment 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
Multi-wavelength measurement
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.
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.
With USB COM port the device can be connected to a PC, which can not only enhance theperformance in data testing and spectrum scanning, but also expand the memory to save more testing results.
● Double beam optical system
● 8-inch color touch-screen
● Automatic zero and full scale adjustment
● Automatic wavelength settings
● Equipped with USB COM port
● UV WIN8 Spectrum Data Processing Software optional
● Thermal plotter optional
and blazed holographic gratings.
