Core Advantages | Why Choose the UPF-620

1. Transient UV Spectrum Acquisition: Full-Band Scan in 1 Second

Advanced 500KHz high-speed spectral acquisition technology fundamentally revolutionizes the slow point-by-point scanning mechanism.Detector arrays enable nanosecond-level synchronous response, completing full-band data collection from UVA to UVB (280–420nm) within 0.1ms integration time. Parallel computing supports the entire workflow—from data capture and signal averaging to UPF result analysis—completed in just 1 second.

Outstanding SNR: Ultra-fast acquisition enables thousands of real-time averages in a very short time, easily achieving SNR > 1000:1, ensuring fast and accurate UPF evaluation.

2. Intelligent Integrated Control System with Built-In Touchscreen

Equipped with a high-performance quad-core industrial processor and an optimized embedded OS, eliminating dependence on external PCs. All operations are performed via an industrial-grade capacitive touchscreen following SOP-driven logic, reducing the learning curve and minimizing errors. From spectrum acquisition and dark current correction to UPF value and UVA/UVB transmittance calculations, a single button initiates automated sequences for seamless “sample-to-result” processing.

3. High Dynamic Range Photodetection: UPF Measurement up to 2000

Research-grade photodetector arrays provide a 50,000:1 dynamic range, capturing signals from highly transparent to extremely opaque fabrics. Quantum efficiency in the UV range reaches ~90%, with cooled detectors suppressing dark noise to <0.1mv/rms. Handles extreme cases of <0.05% transmittance, with sensitivity supporting UPF measurements up to 2000.

4. Ultra-Wide UV Coverage: Comprehensive UVA/UVB Evaluation

Adopting a symmetrical optical path design and research-grade back-illuminated area array detectors, it achieves an ultra-wide ultraviolet spectral measurement range from 280nm to 420nm. This not only fully covers the UVB (280–315nm) and UVA (315–400nm) bands defined by international standards, but also extends the measurement range into the UVA-I long-wave region up to 420nm, ensuring the capture of even the finest spectral details.

Exceeding Standard Requirements: Far surpasses the 400nm upper limit required by standards such as AATCC 183 and AS/NZS 4399, providing decisive data support for evaluating cutting-edge broad-spectrum protective materials.

High-Resolution Analysis: With an optical resolution of 2nm, it can precisely resolve every spectral detail, enabling a more comprehensive and accurate evaluation of textiles’true protective performance against the full spectrum of ultraviolet radiation, ensuring your test results carry indisputable completeness and authority in any context.

5. Global Standards Compatibility: Built-In Authoritative Testing Methods

Preloaded with multiple authoritative international standards, including AATCC 183, AS/NZS 4399, EN 13758, GB/T 18830, and JIS L 1925. The system instantly applies all key parameters of the selected standard—specific wavelength ranges, data step sizes, and UPF calculation weightings—ensuring that every test fully complies with the target regulations.

Structured Update Support: With a modular software architecture, when international standards are updated or new versions are released, you can quickly gain compatibility with the latest standards through a simple software upgrade package. This ensures long-term effectiveness of your investment and keeps you aligned with the international forefront at all times.
