T90+ & T92+ Double Beam UV Visible Spectrophotometer

Double Beam UV-VIS Spectrophotometer

The T 90+ and  T 92+ are a high performance double beam scanning spectrophotometer with a variable spectral bandwidth 0.1, 0.2, 0.5, 1.0, 2.0, 5.0nm.

The Czerny-Turner Monochromator with a holographic grating keeps stray light to a minimum and offers excellent optical resolution. The use of photomultiplier tube as detector delivers exceptional sensitivity.
