Product Description L7 Lab Auto Double Beam UV-VIS Spectrophotometer with Color Touch ScreenL7 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 scanningConcentration 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.Main FeaturesDouble beam optical system 8-inch color touch-screen Automatic zero and full scale adjustmentAutomatic wavelength settings Equipped with USB COM port UV WIN8 Spectrum Data Processing Software optional Thermal plotter optional SpecificatonsPhotometry: Double BeamMonochromator Type: Czerny-TurnerFocal Length: 160mmGrating: 1200 lines/mmDetector: Silicon PhotocellSpectrum Bandwidth: 1.8nmWavelength Setting: 8-inch color touch-screenWavelength Range: 190-1100nmWavelength Accuracy: ±0.3nmWavelength Repeatability: ≤0.1nmStray Light : ≤0.03%T( at 220nm NaI, 360nm NaNo2 )Photometric Range: 0.0-200.0% T -0.301-4.000 A 0.000-9999 CPhotometric Accuracy: ±0.3% T ±0.002 Abs (0-0.5A) ±0.004 Abs (0.5-1A)Photometric Repeatability: ≤0.15% T 0.001 Abs (0-0.5A) 0.002 Abs (0.5-1A)Baseline: ≤±0.002 A(200-1090nm)Noise: 100%(T)noise≤0.15%(T) , 0%(T)noise≤0.1%(T)Drifting: ≤0.0009 Abs/h (250nm and 500nm after 2h warm up)Power: AC220V±22V 50Hz±1Hz, 200WPackaging Size: 710mm X 590mm X 505mm 0.21M3 36kgStandrad AccessoriesOperation manual 1pcGlass cuvette 1cm 4pcsQuartz cuvette 1cm 2pcsPower cable 1pcFuse 2pcsCuvette holder 10mmOptional AccessoriesUV WIN8 Spectrum data processing softwareThermal Plotter
