Product Description WEST TUNE L7 Double Beam UV-VIS Spectrophotometer Double beam optical system8-inch color touch-screenAutomatic zero and full scale adjustmentAutomatic wavelength settingsEquipped with USB COM portUV WIN8 Spectrum Data Processing Software optionalThermal plotter optionalFeatures1,L7 double beam UV-VIS spectrophotometers adopt double beam optical system, and blazed holographicgratings. 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 quantitativetesting, such as:Full-spectrum scanningLinear regressionDetailed spectrum scanningConcentration direct readingTime-based kinetics determinationPeak / Valley detectingGOTO λ Multi-wavelength measurement4,The equipment is designed with sophisticated power protection system. With high capacity ofinternal memory, it can store testing results, scanned images, regression equations and correctiondata. Therefore, it follows a fast initialization when power on.5,The instrument can be connected with dedicated printer, which can print testing results, or drawcurve 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 theperformancein data testing and spectrum scanning, but also expand the memory to save more testing results.SpecificationsModelL7PhotometryDouble BeamMonochromator TypeCzerny-TurnerFocal Length160mmGrating1200 lines/mmDetectorSilicon PhotocellSpectrum Bandwidth1.8nmWavelength Setting8-inch color touch-screenWavelength Range190-1100nmWavelength Accuracy±0.5nmWavelength Repeatability≤0.2nmScanning SpeedFast-Medium-SlowStray Light≤0.03%T( at 220nm NaI, 360nm NaNo2 )Photometric Range0.0-200.0%T-0.301-4.000A 0.000-9999CPhotometric Accuracy±0.3%T±0.002Abs (0-0.5A)±0.004 Abs (0.5-1A)Photometric Repeatability≤0.15%T0.001 Abs (0-0.5A)0.002 Abs (0.5-1A)Baseline≤±0.002A (200-1090nm)Noise100%(T)noise≤0.15%(T) , 0%(T)noise≤0.1%(T)Drifting≤0.0009 Abs/30min (250nm and 500nm after 2h warm up)PowerAC220V±22V 50Hz±1Hz, 200WPackaging Size710mm X 590mm X 505mm 0.21M3 36kgStandard AccessoriesUser manual 1pcGlass cuvette 1cm 4pcsQuartz cuvette 1cm 2pcsPower cable 1pcFuse 2pcsOptional Accessories1.UV WIN8 Spectrum data processing software2.Thermal plotter
