In industries such as powders and masterbatches, precise control of sample color directly determines product quality and market competitiveness. However, these samples often have irregular shapes and uneven particle distribution. Traditional colorimeters, limited by small apertures, struggle to capture the overall color characteristics, leading to large deviations and low testing efficiency. Today, CHNSPEC introduces the brand-new DS-807 Large-Aperture 50mm Spectrophotometer, which, with its ultra-large aperture and outstanding performance, provides a professional solution for measuring the color of non-uniform samples, redefining industry testing standards!
I. 50mm Ultra-Large Aperture for Accurate Coverage of Non-Uniform Samples
To address the pain points of measuring irregular samples such as powders and masterbatches, the DS-807 is the first to feature a 50mm ultra-large measurement aperture, capable of covering a much larger sample area at once. This effectively avoids measurement errors caused by local particle differences and ensures that each data set truly reflects the overall color characteristics of the sample. Whether loose powder raw materials or masterbatches with uneven particle sizes, the DS-807 delivers efficient and precise measurements, thoroughly solving the traditional problem of “inaccurate and incomplete” testing.
At the same time, the instrument adopts a fully sealed measuring port design, effectively preventing particles and dust from entering the interior during testing. This not only protects the cleanliness and stable operation of core components, extending the instrument’s service life, but also avoids deviations caused by internal contamination, providing reliable assurance for long-term precision testing.
II. Robust Performance for a Professional Measurement Experience
As a professional-grade spectrophotometer, the DS-807 demonstrates unparalleled advantages in technical specifications. Using a D/8 illumination method (including specular reflection, SCI), paired with a 100mm integrating sphere and a full-spectrum balanced LED light source, it covers the 400–700nm wavelength range, precisely capturing color information across different bands to meet the demanding testing requirements of powders and masterbatches.
In terms of data accuracy and stability, the DS-807 excels. The repeatability standard deviation ΔEab is controlled within 0.03, and inter-instrument agreement ΔEab ≤ 0.4. Even when comparing results across multiple devices, data consistency is ensured, providing strong support for standardized quality control. With a rapid ≈1-second measurement time, detection efficiency is greatly improved, making batch testing scenarios easy to handle. Meanwhile, its 10-year, 2-million-use light source lifespan eliminates frequent replacement, reducing maintenance costs and ensuring long-term reliability.
The instrument is also equipped with a 7-inch IPS full-view LCD screen, supporting both Simplified Chinese and English operation. The interface is simple and intuitive, enabling quick mastery without professional training. With storage capacity of up to 10,000 test records, it meets the need for large-scale data retention. The built-in USB port makes data export and subsequent analysis convenient, providing complete support for quality traceability and process optimization.
III. Versatile Accessories for Diverse Measurement Scenarios
To further expand its application range, the DS-807 offers two optional accessories to meet different sample measurement needs. The 800 quartz cylindrical cuvette, with excellent transparency, is suitable for color measurement of liquids, ensuring accurate and reliable results. The plastic petri dish is designed for granular and powder samples, making handling and testing more convenient while avoiding contamination.
Out of the box, the instrument comes with petri dishes, a black chamber, a white calibration tile, data cable, and power cable—ready to use without additional purchases. This saves users time and cost, allowing them to quickly start efficient testing.
From incoming quality inspection of powder raw materials, to process monitoring in masterbatch production, to consistency testing of finished products, the DS-807 Large-Aperture 50mm Spectrophotometer stands out as a “powerful assistant” for quality control in powders and masterbatch industries. With its ultra-large aperture, precise performance, and convenient operation, it not only helps enterprises improve product color consistency and reduce rework and waste caused by deviations, but also supports the establishment of standardized quality management systems, enhancing market competitiveness.
Now officially launched, the DS-807 Large-Aperture 50mm Spectrophotometer is the ideal solution if you are facing challenges in measuring non-uniform sample colors and want to improve quality control through professional equipment. Choose the DS-807 to safeguard your production and inspection with precise measurements, and open a new chapter of efficient quality management!
