The UV1900 series is a new generation of double beam UV-Visible Spectrophotometers. The instruments are professionally manufactured to a very high specification, with excellent quality control. This ensures high performance characteristics, flexibility and user friendliness.

Features:
The UV1901 and UV1902 have a wavelength range of 190nm to 1100nm. The only difference between the UV1901 and UV1902 is the bandwidth which is at 1 nm in the UV1901 while it is at 2nm in the UV1902 instrument.

UV1900 series has excellent optical performance and lower stray light. The advanced circuit measurement and control system ensures the machine with high stability and extremely low noise. The detachable sample chamber can accommodate varied accessories to suit different applications user may encounter. The design of open spacious light source chamber allows unique pre-aligned deuterium and halogen lamp for easy lamp replacement to avoid optical adjustment.

Function:
The UV1901 and UV1902 are able to carry out the following analysis: photometric, spectrum, advanced quantitative and kinetics measurement. When interfaced to a PC the software offers many more applications and analysis.

UV1900 series is extensively used for the analysis of foods, drugs, agricultural products and is widely used in organic, inorganic, petroleum, pharmacy, environmental, bio-chemistry, optics,metallurgy, mineral institutes and industries.
