xtester-L7 Cheap Spectrometer Dual Double Beam UV-VIS Spectrophotometer

Features


1. L7 double beam UV-VIS spectrophotometers adopt double beam optical system, and blazed holographic gratings. They have outstanding test precision and very competitive prices.
2. 8-inch color touch-screen, cutting-edge user interface, powerful functions, and easy operation.
3. With powerful functions, the equipment shows great performance in qualitative and quantitative
4. 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.
5. 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.
6. With USB COM port 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.

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
