- PRODUCT DETAIL
EU-2200 UV-Visible Spectrophotometer
Product Introduction
The EU-2200 UV-Visible Spectrophotometer is a single-beam analytical instrument designed for ultraviolet and visible light measurements across a wavelength range of 190–1100 nm. It supports transmittance, absorbance, and energy measurement modes, as well as quantitative analysis using coefficient-based calculations and standard curves.
The instrument combines a high-performance 1200 lines/mm diffraction grating, an imported silicon photodiode detector, and long-life tungsten and deuterium lamps. Automatic wavelength setting, light-source switching, dark-current correction, and blank correction help simplify routine laboratory operation.
With a large dot-matrix LCD, membrane-key interface, onboard data storage, and serial and USB connections, the EU-2200 is suitable for routine analytical testing, quality control, education, and research. Optional PC connectivity functions support time scanning, data processing, and report printing.

Working Principle
The EU-2200 operates using the principle of ultraviolet-visible spectrophotometry, measuring the interaction between light and a sample.
1. Light generation: Tungsten and deuterium lamps provide light for visible and ultraviolet measurements.
2. Wavelength selection: A 1200 lines/mm diffraction grating separates the light into individual wavelengths.
3. Sample measurement: Selected light passes through the sample, and the instrument measures the transmitted light intensity.
4. Signal conversion: The silicon photodiode detector converts the detected light into an electrical signal.
5.Photometric calculation: The instrument calculates transmittance, absorbance, or energy values.
6. Quantitative analysis: The coefficient method or standard-curve method can be used to determine sample concentrations.
7. Data processing: Results and standard curves can be stored internally and transferred to a computer. Optional PC functions provide time scanning and report generation.
