Core Advantages | Why Choose the UPF-660 Series
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
(250–420nm) 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 250nm 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.
