L6S/L6/L3S /L3

Single Beam UV VIS Spectrophotometer

* Split beam optical system Automatic wavelength settings

* 8-inch multi color touch-screen

* automatic 8 position cuvette holder

* Automatic zero and full scale adjustment Equipped with USB port

* Thermal plotter optional

* Software optional

Common 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.
