ZHONGWANG UV1900 serial Double
Beam Spectrophotometer
UV1900 series
Introduction:
The
UV1900 series is a new generation of double beams 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.
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.
The
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.
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.
