In outdoor apparel, sports equipment, baby products, and other fields, the ultraviolet protection performance of textiles is one of the core indicators of product quality. However, traditional testing equipment suffers from slow detection speed, low data accuracy, and inconsistent standards, making it difficult to meet the stringent demands of enterprises for sun-protective fabric R&D, production quality control, and global market access. Today, this industry pain point is solved — CHNSpec UPF-660 Series Textile Ultraviolet Protection Factor Analyzers debut with cutting-edge spectroscopy, intelligent control, and full-spectrum standard compatibility, delivering a revolutionary solution for fabric sun protection performance testing.
I. Five Core Advantages — Creating the “All-in-One Tool” for Sun Protection Testing
1. Instantaneous UV Spectral Acquisition — Full-Band Scanning in One Second
Traditional point-by-point scanning instruments often take several minutes to complete one test, resulting in inefficiency and unstable data. The UPF-660 Series adopts advanced 500 kHz high-speed spectral acquisition combined with a nanosecond-response detector array, achieving full-spectrum data collection (250–420 nm) with just 0.1 ms integration time. With powerful parallel computing, the entire process — from data acquisition, signal averaging to UPF calculation — can be completed within one second, representing a qualitative leap in efficiency.
Moreover, this ultra-fast acquisition supports real-time averaging of thousands of measurements, easily achieving a signal-to-noise ratio (SNR) > 1000:1. Even minute variations in UV transmittance can be captured with precision, providing solid data for UPF evaluation.
2. Intelligent All-in-One Control — Standalone Instant Analysis
Breaking free from dependence on external PCs is a key breakthrough of the UPF-660 Series. Equipped with a high-performance quad-core industrial processor, optimized embedded OS, and a 7-inch IPS full-view industrial capacitive touchscreen, all operations can be done on the device itself. From spectral acquisition and dark current correction to UPF and UVA/UVB transmittance calculation according to international standards, every step can be completed with a single tap.
This SOP-driven workflow significantly lowers operational barriers, avoids errors, and allows both R&D staff and QC operators to use the device with ease, greatly improving efficiency.
3. High Dynamic Range Detection — UPF Measurement Up to 2000
To address the challenge of testing highly opaque or ultra-protective fabrics, the UPF-660 Series is equipped with a scientific-grade high dynamic range detector array, delivering a 50,000:1 dynamic range. It can measure fabrics with high transmittance as well as extreme low transmittance below 0.05%. With UV quantum efficiency close to 90% and advanced cooling suppressing dark noise to <0.1 mV/rms, the system ensures stable, clear signals even at millisecond exposures. The UPF measurement upper limit reaches 2000, satisfying the strictest demands of premium sun-protective fabrics.
4. Ultra-Wide UV Coverage — Accurate Full-Band Evaluation
International standards mainly focus on UVB (280–315 nm) and UVA (315–400 nm). The UPF-660 Series, however, leverages symmetrical optical design and back-illuminated scientific-grade detector arrays to extend the range to 250–420 nm, covering not only standard requirements but also the UVA-I region (400–420 nm). This ensures finer spectral detail capture.
With 2 nm optical resolution, every spectral detail can be precisely analyzed, delivering comprehensive and authoritative evaluation of textile UV protection.
5. Global Standard Compatibility — Long-Term Effective Investment
To meet varying international requirements, the UPF-660 Series comes preloaded with authoritative test methods including AATCC 183, AS/NZS 4399, EN 13758, GB/T 18830, and JIS L 1925. The system automatically locks parameters such as wavelength range, step size, and UPF weighting factors, ensuring every test complies with the target regulation for seamless global market access.
With its modular software architecture, future updates to international standards can be easily adopted via software upgrades — no hardware replacement needed — safeguarding long-term ROI and keeping the system aligned with international benchmarks.
II. Robust Technical Specifications — Foundation of Accuracy
The UPF-660 Series boasts superior technical parameters across the board. All three models (UPF-600/620/660) adopt a D/0 geometry (integrating sphere illumination, 0° viewing angle). The integrating sphere is FPET-coated, with an aperture of 1.27 cm and an exposed sample area of 1.26 cm². A pulsed xenon lamp serves as the light source, delivering UV energy <0.2 J/cm² per measurement cycle, with a lamp life exceeding 100 million flashes for long-term stability.
