CS-810 Transmitted Spectrophotometer. The ETC(Every Test Calibration) means the instrument will calibrate the system’s hardware and software in each measurement. This technology has totally  solved normal color measurement instruments’ problem about the stability of long term measurements and data drift. Technology has lots of national invention patents in the technology.

In addition to the ability of measuring the transmittance of materials, the instrument can also measure  the APHA/PtGo and Gardner chromatic scale of products like resin, solvent, acid, perfume and varnish. As well as to measure the Seybold chromatic scale of gasoline, white oil, kerosene, lubricating oil and paraffin  oil. The technologies eliminate the subjectivity of visual chromaticity and provide a better sensitivity and the largest repeat-ability.

The instrument can be connected to color management software through PC so it is convenient for enterprises’ quality monitoring and color data management. It can also make user’s color management  digital, compare the color difference, generate test report, provide kinds of spatial measurement data and  customize user’s color management.

Professional design standard, powerful function configuration
●instrument uses globally accepted D/0(integrating sphere diffused lighting, 0 degrees observer),
both SCI and SCE included lighting and observation conditions.
●use CLEDs light source-LED light source that has balanced intensity across visible spectrum deficiency in
certain parts of the spectrum in common white LEDs, and guarantees the speed of the measurement and
the accuracy of the measurement results.
●it uses innovative ETC(Every Test Calibration);standard white board is included in the optical system, and
therefore has reliable accuracy and repeatability in every measurement
●SCS optical engine, creates the best measurement repeatability for spectrophotometers in the industry,
and guaranteed accurate measurement of surface color of materials.
