Product Description L7 Double Beam UV-Vis Spectrophotometer1 double beam optical system2 8-inch color touch-screen3 automatic zero and full scale adjustment4 automatic wavelength settings5 equipped with USD COM port6 UV WIN8 spectrum data processing software optional7 thermal plotter optional Features1 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 testing, such asFull-spectrum scanningDetailed spectrum scanningTime-based kinetics determinationGOTO λLinear regressionConcentration direct readingPeak-/valley detectingMulti wavelength measurement4 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-base 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.
