CM-825Desktop spectrophotometer

1、 Instrument Description

Desktop spectrophotometerCM-825It has excellent inter station deviation, high precision, and reproducibility. Regarding the exchange of color data between upstream and downstream or inspection of incoming and outgoing goods, as well as the color matching of coatings and inks.

Motor driven mirror reflection inserts can easily measure changes in color data of mirror or diffuse reflections. adjustableUVThe control device can automatically emit ultraviolet light(UV)Adjust to natural through precise filtersD65In the sunlight sourceUVmagnitude Simultaneously configure two pre-set settingsUVAdjust the frequency band

The large screen display makes it easy for you to view or directly change the instrument settings,Use matching color quality control software or color matching software(ColorMatch)You can choose the option to change the instrument status from the instrument or software. It has the function of measuring transparent and semi transparent color samples, and the configured color sample fixture can be used to conveniently measure the transmittance of transparent color samples. Provide measurements on semi transparent color samples“turbidity”The function.

The design of a dual spectrum analyzer ensures the long-term stability and measurement accuracy of the instrument by simultaneously obtaining measurement color samples and reference data from the internal environment for calculation. Improve the reproducibility, stability, and inter stage variability of the instrument.

High concentration pulsed xenon lamps can accurately read readings of dark or high concentration colors, and use noise ratio signals to eliminate all effects on surrounding light. No heat is generated and no preheating is required.
