  • High wavelength accuracy:The built-in spectral characteristic wavelength of the instrument automatically detects and calibrates the wavelength to ensure the accuracy and long-term stability of the wavelength.

    Wide wavelength range:The wavelength range of the instrument covers 190nm to 1100nm, reaching the widest wavelength range of instruments of the same grade, meeting the wavelength requirements of most spectrophotometric analysis and testing.

    High-speed scanning:The scanning speed is multi-level optional, using high-precision wavelength driving mechanism, with high-precision stepper motor subdivision technology and high-speed digital signal processing technology, the maximum wavelength scanning speed can reach 7000nm/min, and the wavelength moving speed is higher than 10000nm/min. High-speed scanning can help users to capture the instantaneous spectral changes of samples and improve work testing efficiency.

    High photometric accuracy:The overall aluminum alloy die-casting mold is used to ensure that the optical optical path meets the measurement design requirements, improves the process assembly efficiency, and achieves high photometric accuracy test indicators.

    Stand-alone U disk storage:Equipped with U disk storage function, the quantitative data of stand-alone test is stored in U disk, and the file format is compatible with application software such as Excel, which is convenient for users to manage data.

    The single-machine quantitative analysis function is rich:The electronic system adopts a 32-bit ARM core processor system and is equipped with a 128×64 large-screen liquid crystal display. The single-machine quantitative analysis function can perform multi-wavelength testing, standard curve fitting and measurement, standard coefficient equation input, standard equation reading and storage, data Storage and printing, concentration quantitative test and other functions.

    Light source replacement is convenient: The deuterium lamp of the instrument is fixed by a universal flange, and the replacement of the deuterium lamp can be completed with the operation of two screws, without the need for optical path adjustment, which makes the maintenance of the instrument simpler and more reliable.

    USB communication mode: The instrument uses USB to connect to the computer, with high interface penetration rate, fast communication speed and high degree of automation. Compared with the traditional RS232 serial port, users can realize online communication without any parameter setting.

    Powerful software: the software can realize spectrum scanning, time scanning, kinetic test, quantitative analysis, multi-wavelength analysis and formula calculation, spectrum processing, peak and valley search, printing data, DNA/RNA test, instrument calibration, performance verification, etc. functions to meet various requirements in different areas of analysis.
