  • Basic Introduction
    DSCD-920 Transmitted liquid Tabletop Spectrophotometer is good performance and specially designed for testing the liquid transmittance, absorbance, concentration, chrominance and other parameters. The instrument adopts the measurement structure of D/0, integration of the full band LED composite light source, double beam optical system, ETC every-time calibration technology, which makes the instrument reaches a resolution of 0.0001, deviation of the transmittance within 0.08% and chromatic value: △E*ab 0.015.

    Brief Introduction
    • Transmission D/0 Structure and Reflection D/8 Structure

    • Double Optical Paths Spectral Analysis Technology
    It could get the measurement sample data and internal environment data at the same time to make sure the testing accuracy and stability for long time running.

    • Compatible with SCI/SCE Measurement
    Adopt D/8 illuminant condition recommended by the CIE to meet the color testing requirement for different industries. It could measure with SCI and SCE to see the color data change more clearly.
    • Four Testing Calibers
    It is easy to adjust the testing calibers. The largest caliber diameter reaches 25.4mm. It could test the sample with different sizes.
    • Large screen display and Stand-alone operation
    • Unique Calibration Board Design
    • Flexible Test Fixture
