  • Benchtop Spectrophotometer (Reflectance and Transmittance) DSCD-920 adopts 7 inches touch screen, full wavelength range, Android operate system. Illumination : reflectance D/8° and transmittance D/0°(UV included / UV excluded), high accuracy for color measurement, large storage memory, PC software, because of above advantages, it is used in laboratory for color analysis and communication

    • Adopts reflectance D/8° and transmittance D/0° geometry to measure both opaque and transparent materials.

    • Dual Optical PathsSpectrum Analysis Technology
    This technology can simultaneous access to both measurement and instrument internal environmental reference data to ensure instrument accuracy and long-term stability.

    • Compatible with SCI/SCE measurement, Support SCI+SCE Measurement
    Instrument adopts D/8 geometry which is highly recommends by CIE (International Commission on Illumination) to meet color measurement of different industries.It supports both SCI (specula component included) and SCE (specular component excluded) mode for better detect of color change.Fast SCI+SCE measurement, test time only need less than 4s.

    • Rotatable Touch Screen with Android Operate System
    Screen position and direction can be adjusted according to the instrument test methods.

    • Open Transmittance Measurement Area, no limit on sample size

    • Different Kinds of Accessories for simple measurement
    It contains 15 kinds of standard and 12 kinds of optional accessories to measure different kinds of materials

    • Accessory Drawer to Protect and Store Accessories

    • Switchable Reflectance Apertures

    • Four Kinds of UV Test Modes for Fluorescence Material Measurement
