  • lUV1900 series double beam UV-Vis spectrophotometer adopts rigorous and precise double beam optical system and circuit control system design, high-quality instrument determines its high standard accuracy, repeatability, low noise and low stray light indicators and excellent stability and linear range.

    lThere are two bandwidth configurations, 1nm and 2nm, suitable for different users to choose.

    lThe instrument uses Hamamatsu deuterium lamp and Osram long-life halogen tungsten lamp, which is convenient for lamp source replacement.

    lThe large-screen 6-inch 320×240 dot matrix digital LCD display with backlight makes the instrument easy and intuitive to operate.

    lDetachable structure of the sample chamber design, users can choose measurement accessories such as reflection sample holder, solid sample holder, etc., to meet the needs of analysis and testing in different application fields.

    lThe Chinese and English operating software developed under the Windows environment provides a rich and unique analysis system.

     

    Dedicated analysis software:

    UV1900 series dual-beam UV-Vis spectrophotometer special analysis software for qualitative and quantitative data processing - UVCON control software developed under Windows environment, which can control the operation of the host, including data acquisition (single-point, multi-point measurement, spectral scanning, Quantitative determination, time scanning and DNA determination) and various data processing to help complete analytical research in many fields from routine quality control to environmental protection, biochemistry, medical hygiene, and materials.

     

    The main function:

     

    Photometry Simultaneous measurement of transmittance and absorbance at 1 to 6 wavelengths
    Spectral measurement Perform transmittance, absorbance, reflectance and energy spectrum scanning in the wavelength range, and can perform various data processing such as peak-valley detection, derivative calculation, spectrum calculation, etc.
    quantitative measurement Single-wavelength, dual-wavelength, three-wavelength and multi-wavelength determination; 1-9 points working curve (1-3 times) regression
    Kinetic assay Time scan of transmittance and absorbance at arbitrary wavelengths and various data calculations
    data output Data files and parameter files can be accessed, and measurement results are output in standard and common data file formats
