Why Choose Qualitest for Your UV Weathering Needs
With more than two decades of experience supplying advanced testing and analytical instruments to laboratories, manufacturers, and research institutions across more than 60 countries, Qualitest delivers premium UV-weathering performance backed by global expertise in standards-compliant materials testing.
Three-Tier Portfolio — One Trusted Source
From the entry-level benchtop QualiUV™ 100 for basic UV testing through the full-feature QualiUV™ 200 for ISO 16474 / ISO 11507 / ISO 4892 / ASTM G154 compliance, plus the dedicated Irradiance Radiometer & Calibrator for chamber calibration — Qualitest offers a coordinated portfolio that matches every laboratory size, budget, and test-protocol requirement.
US-Made Fluorescent UV Lamps for Consistent Results
The QualiUV™ 200 uses US-manufactured UVA-340 and UVB-313 fluorescent lamps developed from over 40 years of fluorescent-technology expertise. These lamps maintain consistent spectral power distribution for up to 6,000 hours of operation — delivering more reliable test outcomes, fewer lamp replacements, and lower lifecycle operating cost than competing Xenon-arc or low-grade UV alternatives.
Comprehensive Weathering Simulation
The QualiUV™ 200 delivers the most realistic real-world simulation: a 12-nozzle (6 per side) water-spray system mimics sudden rainstorms and heat-shock cycles; the unique condensation system heats chamber-bottom water to superheated steam and maintains 100% relative humidity to simulate dew exposure (the dominant outdoor moisture mechanism); and the BST black-panel thermometer with Pt 100 sensor delivers automatic high-precision temperature control throughout every cycle.
Full International Standards Compliance
Qualitest UV chambers are engineered to meet the world's leading weathering standards: ISO 16474-1 (general guidance), ISO 16474-3 (fluorescent UV lamps), ISO 11507 (paint exposure to UV + water), ISO 4892-1 (plastics weathering general guidance), and ASTM G154 (UV-fluorescent operation). This ensures every test result is universally accepted, audit-ready, and defensible in regulatory and customer reviews.
User-Editable Programs & Intuitive Interface
The QualiUV™ 200 features an intuitive HD color touchscreen for all controls. Operators can edit up to 10 different test segments per program — combining irradiation, water spray, condensation, and rest phases with custom parameters — and save up to 6 programs for instant recall. This dramatically reduces setup time and ensures reproducibility across test campaigns.
Cost-Effective Value & Global Support
Qualitest delivers premium UV-weathering performance at a transparent, competitive price point — backed by overseas installation, operator training, stocked spare parts, and lamp regrind/replacement support. With offices and authorized partners across the USA, Canada, UAE, KSA, GCC, EU, India, APAC, Africa, and Latin America, expert support is always within reach.
