PG Instruments - Model T92+ -Spectrophotometer

The T92+ is a high performance double beam spectrophotometer with a variable spectral bandwidth from 0.1-5nm, selected by a continuous variable slit.

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

The T92+’s true double beam optical system coupled with an efficient and well proven electronic control system ensures high stability and low background noise.
