Product Description: Experience Unmatched Color Precision with the 3nh ST70 Spectrophotometer The 3nh ST70 Spectrophotometer, part of the advanced TS series, sets a new benchmark in color measurement. Built on core TS series technology, it features a dual 32-group photodiode array sensor and full-spectrum LED light source, ensuring rapid, precise, and reliable results. Engineered for professionals across industries—including plastics, paint, textiles, printing, and ceramics—the ST70 delivers exceptional accuracy even for fluorescent samples. Key Benefits: Superior Accuracy & Repeatability: Achieves repeatability within ΔEab 0.02 and inter-instrument error within ΔEab 0.15 for precise color consistency. Versatile Apertures: Comes standard with 5 apertures (8mm flat/tip, 4mm flat/tip, and 1x3mm tip) to handle various sample types. Fast & Reliable: Measures in just 1.5 seconds with support for both SCI and SCE modes, meeting international standards (CIE No.15, ISO7724-1, ASTM E1164, and more). Camera-Assisted Targeting: Built-in camera ensures accurate alignment with your measurement area, improving efficiency and precision. Robust Connectivity: Compatible with Huawei Harmony OS, Android, iOS, WeChat applets, and Windows, offering seamless integration via USB and Bluetooth® 5.0. Advanced Calibration: Features non-contact automatic calibration with a durable, imported whiteboard for long-term accuracy. Applications: Perfect for color quality control in plastic electronics, paint & ink, textiles & garments, ceramics, printing, and more. Supports fluorescent sample testing with high sensitivity across the 360-780nm spectrum. Product Features: Dual 32-Group Photodiode Array Sensor: Ensures high light sensitivity and wide spectrum response for consistent and stable results. D/8 Optical Geometry & SCI/SCE Mode: Delivers industry-standard color readings with quick SCI+SCE measurements. Full Spectrum LED + UV Light Source: Avoids spectral gaps and supports precise fluorescence measurement. Five Measurement Apertures: Adaptable for various sample sizes, including ultra-small areas (1x3mm tip). Real-Time Camera Positioning: Confirms measurement accuracy visually. Automatic Calibration: Hands-free calibration with a professional-grade, wear-resistant whiteboard. Extensive Color Space & Light Source Options: Supports 10 color spaces (CIE LAB, XYZ, LCh, etc.) and 41 illuminants (D65, A, CWF, TL84, LEDs, and customizable options). Comprehensive Color Indexes: Measures spectral reflectance, whiteness, yellowness, metamerism, opacity, gloss, and more.
