Product Advantages:
Accurate Measurement: Provides high-precision evaluation of key UV protection metrics like SPF, UPF, and UVA/UVB protection.
Rapid Detection: Offers significant time savings compared to traditional in vivo or some chemical analysis methods, improving laboratory throughput.
Multi-Scenario Application: Versatile enough to test a wide range of products and materials with UV protective claims beyond just cosmetic sunscreens.
Objective Results (In Vitro): Provides objective data based on spectral measurements, reducing variability associated with subjective or biological tests.
Non-Destructive Testing (for materials): For textiles and films, the in vitro method typically does not damage the sample.
Supports R&D and Formulation: Provides quick feedback on the UV performance of different formulations and material compositions during development.
Ensures Regulatory Compliance: Helps manufacturers meet the testing requirements stipulated by international regulatory bodies and standards organizations.
Functional features:
Accurate measurement:
It can measure the key indicators of sunscreen products such as the sun protection index (SPF value), ultraviolet protection factor (UPF), and protection against UVA and UVB with high precision, providing accurate data for product quality evaluation.
Rapid detection:
It can complete the measurement and analysis of samples in a short time, which greatly improves the detection efficiency and saves time and cost compared with traditional manual testing or chemical analysis methods.
Multi-scenario application:
It is not only used for the research and development, production and quality inspection of sunscreen cosmetics, but also can be applied to the testing of sunscreen textiles, sunscreen functional materials, sunscreen additives and other fields to evaluate the sunscreen performance of different products.
Key Features:
Solar Shield Assessment: This UV tester has a Hamamatsu flicker Xenon lamp for measuring wide-range wavelength scanning. It is also capable of measuring fluorescent samples.
Wavelength Test Range: This UV tester measures UV wavelengths between 280 and 400nm. It ensures the precise measurement of fabric’s UPF, which measures how much UV rays can be blocked, transmitted, and absorbed by fabric.
Compatibility: This UV tester is compatible with AATCC, BS, EN, AS, and GB/T standards. This worldwide compatibility makes it results accurate and reproducible.
Automation: This fabric UPF tester offers easy automation through automatic data processing abilities, including graphs, charts, analysis, and test reports.
Technical Parameters:
Light Source: 125W DC continuous xenon light source, with spectral characteristics close to those of the sun.
Wavelength Range: 290-400nm, with scan steps of 1nm, 2nm, and 5nm.
Wavelength Accuracy: Wavelength accuracy is 0.2% (0.58 nm – 0.80 nm), with wavelength repeatability of 0.25nm.
Function: Automatically scans multiple locations, automatically calculates or measures SPF values, displays UVA/UVB values, and prints test reports and graphs.
Applications: Suitable for measuring SPF values in cosmetics, sunscreens, UV-resistant fabrics, and photographic emulsions.
