EU-2200 Ultraviolet and Visible Spectrophotometer

Product Introduction
The EU-2200 Ultraviolet and Visible Spectrophotometer is a single-beam UV-Vis spectrophotometer designed for accurate measurement of transmittance, absorbance, and energy across a 190–1100 nm wavelength range. It combines automatic wavelength setting and calibration, dark current blank correction, low stray light, low noise, and high photometric accuracy.
The EU-2200 supports both direct coefficient calculations and standard-curve quantitative analysis. With PC connectivity, users can perform dynamic scanning, map data processing, data management, and report printing, making the instrument suitable for routine laboratory quantitative and spectral analysis.

Performance Features
• 190–1100 nm wavelength coverage for ultraviolet and visible spectral analysis.
• Single-beam optical system with a high-performance 1200 lines/mm grating.
• Imported silicon photodiode detector and long-life tungsten/deuterium light sources.
• High photometric accuracy with low stray light and low baseline drift.
• Automatic wavelength setting and automatic light-source switching.
• Automatic wavelength calibration and dark current blank correction.
• Lattice LCD display with thin-film button keyboard and user-friendly operation.
• Stores standard curves and test data with power-off data retention.
• ARM-based electronics and imported key components for reliable operation.
• PC online functions support dynamic scanning, data processing, and report printing.
• Serial and USB interfaces provide convenient data communication.

Working Principle
The EU-2200 uses a single-beam UV-Vis optical system. Light from the tungsten lamp or deuterium lamp is separated by a high-performance grating into different wavelengths. The selected monochromatic light passes through the sample, and the imported silicon photodiode detects the transmitted optical signal.
The instrument calculates transmittance and absorbance from the measured optical signal. For quantitative analysis, concentration can be determined using either a coefficient method or a standard curve generated from reference standards. Automatic wavelength calibration and dark-current correction help maintain measurement accuracy and stability.
