Double Beam UV-VIS Spectrophotometer
T 90 + dan T 92+ adalah kinerja tinggi balok ganda scanning spektrofotometer dengan variabel bandwidth spektral 0,1, 0,2, 0,5, 1,0, 2,0, 5.0nm.
The Czerny-Turner monokromator dengan kisi hologram membuat cahaya nyasar ke minimum dan menawarkan resolusi optik yang sangat baik. Penggunaan tabung photomultiplier sebagai detektor memberikan sensitivitas yang luar biasa.
