Characteristics/Features

UV1900 is a double-beam UV/VIS Spectrophotometer 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 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.
It's very simple to replace the lamp: after loosening a few screws, the lamp will be at the optimal position without complicated light-adjustment.
UV1900 is protected by software program to restore the instrument to normal work status in case of a power failure.
Being an excellent practical UV/VIS spectrophotometer, UV1900 provides 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.
