Aoda L7 Double Beam UV-VIS Spectrophotometer

Aoda L7 Double Beam UV-VIS Spectrophotometer

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

● GOTO λ

● Multi-wavelength measurement

L7 double beam UV-VIS spectrophotometers 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.

L7 double beam UV-VIS spectrophotometers 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.
