L3S Split Beam VIS Spectrophotometer

Product Details

L3S Split Beam VIS Spectrophotometer survey optical system, and blazed holographic gratings. They have outstanding test precision and very competitive prices. 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
● GOTO λ
● 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.
