UN-650 UV-VIS-NIR Spectrophotometer
Cov yam ntxwv ntawm cov cuab yeej
1.Siv lub classical Czerny-Turner optical qauv, nws cov qauv yooj yim, siab precision, zoo spectral daws teeb meem;
2.Kev tswj qhov system: siv lub tshuab computer tsis siv neeg tswj, tsis siv neeg calibration, tsis siv neeg cov ntaub ntawv sau thiab ua, tshwj xeeb aircraft, yooj yim los tswj.
3.Cov cuab yeej siv dav dav ntawm inlet photomultiplier tube (PMT) thiab lead sulfide (PbS) dual receiver, uas muaj cov teeb liab rhiab heev, tsis tshua muaj suab nrov thiab raug siab dua.
4.Lub software muaj lub luag haujlwm ntawm tsis siv neeg rov pib dua, ntsuas qhov ntsuas qhov ntsuas, cov ntaub ntawv qhia txog lub sijhawm, kev ua cov ntaub ntawv spectral, cov ntaub ntawv xa tawm thiab ntshuam (cov ntawv nyeem, EXCEL), thiab kuaj cov ntawv luam tawm.
5. Cov software ua haujlwm raws li Windows XP, Windows Vista, Windows 7, Windows 8, Windows 8.1, thiab Windows 10 systems.
