Science Laboratory Instrument UV1900 UV/Vis Double Beam Spectrophotometer

Introduction of UV/Vis Double Beam Spectrophotometer

UV1900 series are double beam UV/VIS Spectrophotometers with a scanning function, wider range of spectrum and the highest quality components. Due to its built-in micro-computer system, plus excellent optical and electric circuit system, rational mechanical structure and a large LCD display screen, the instrument is effective and useful for lab analysis in industries.
UV1900 series UV/VIS Spectrophotometer is very easy to learn and the user-menu on the large LCD screen allows every item to be chosen and accepted corresponding to each operational step. 
Being excellent practical UV/VIS Spectrophotometers, UV1900 series provide fast and simple analytical methods to be widely used in organic, inorganic, petroleum, pharmacy, environment, bio-chemistry, medicine, food and other national economy departments for QC and QA.
