• Thermal plotter optional Software optional

Features

1,Legend series spectrophotometers adopt split beam survey optical system, and blazed holographic
gratings. They have outstanding test precision and very competitive prices.
2,8-inch multi color touch-screen, cutting-edge user interface, powerful functions, and easy operation.
3,The automated 8 position cuvette 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

Linear regression
Detailed spectrum scanning
Concentration direct reading
Time-based kinetics determination
Peak / Valley detecting
GOTO λ 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.
