• Integrated lamp power supply for improved stability and reliability
• Automatic functions:
Auto zero adjustment
Auto full-scale calibration
Linear regression calculation
Direct concentration readout
• UV region extended down to 195nm high-sensitivity detection
• Dynamic testing with timed data printing capability
• Continuously adjustable slit width (0–2mm) for flexible analysis conditions
• Stable single-chip microcomputer control system
• High precision optical system for accurate spectral measurement

Working Principle
The UV751GD UV-Vis Spectrophotometer operates based on the principle of light absorption spectroscopy.
• A light source emits radiation across UV, visible, and near-infrared wavelengths.
• The monochromator selects a specific wavelength beam (195–1000nm range).
• The beam passes through the sample cuvette.
• The detector measures the intensity of transmitted light.
• The system calculates:
Transmittance (T%)
Absorbance (A)
Concentration (C)
According to the Beer-Lambert Law, the absorbance is directly proportional to the concentration, enabling accurate quantitative chemical analysis.
