Alpha-1102 Single Beam Visible Spectrophotometer


Alpha-1102 visible spectrophotometer is widely used in the areas like food hygiene, pharmaceutical analysis, teaching, researching etc. With the high accuracy, stability and durability, it can meet different kinds of testing requirements.


With a powerful automatic control system, the instrument can automatically set the wavelength, 0%T and 100%T and the value of A, T, C which can be displayed on the screen directly. Other Functions include zero-error T/A conversion, self-checking, correcting and resetting etc.

Good operating performance: By advanced microcomputer technology and electronic control system, we optimized the traditional optical and structural design. Key components such as holographic grating and detector are all imported from famous brands abroad. It functions a low stray light and high stability and reliability.

Prompt menu for simple operation and easy expandability. Large memory capacity can save more than 200 curves and 500 sets of data. With built-in thermal printer, curves and data can be directly printed out. By USD connection to the PC software, the instrument can be operated by computer.

Other functions include basic photometric test, quantitative test and creation of standard curves and the linear equations. You can curves and equations to use at any time.

The panel with a rational layout design makes users feel comfortable to use.

Complete data analysis functions: Basic photometric mode, quantitative test, Kinetics test etc.

Quantitative test: automatically create the standard curve, alternative fitting and correction methods-single wavelength method, dual wavelength method and three point method. Standard curve data savings.

Kinetics analysis: Enzyme reaction rate calculation for Kinetics.

High resolution large screen graphic LCD display with abundant instructions.Built in thermal printer output data and curves.

Memory function: Up to 1000 test data can be saved in local memory.

By USD connection to the PC software, the instrument can be operated by computer.
