Product Description

Product Description

UV1900 Series Dual-Beam Ultraviolet-Visible Spectrophotometer

The UV1900 series dual-beam ultraviolet-visible spectrophotometer is a high-performance analytical instrument designed for precise laboratory measurements. It adopts a rigorous and precise dual-beam optical system and circuit control system, ensuring excellent performance in multiple key indicators:
High accuracy: Meets strict standards for measurement precision, ensuring reliable data results.
Excellent repeatability: Stable measurement performance, minimizing data deviation between repeated tests.
Low noise & low stray light: Reduces interference factors, ensuring the clarity and accuracy of measurement signals.
Exceptional stability & wide linear range: Maintains consistent performance during long-term operation and adapts to different concentration ranges of samples.
The core design of this spectrophotometer lies in its spectroscopic system: it divides the light source into two independent beams. One beam passes through the sample cell, while the other goes through the reference cell. Both beams alternately illuminate the same high-sensitivity detector. Through real-time comparison of the sample light signal and the reference light signal, the instrument automatically deducts background interferences such as light source fluctuations and solvent absorption. This design fundamentally enhances the stability and accuracy of measurements, making it a trusted choice for laboratory analysis.
