ISO 4892, ISO 16474, ASTM G154 Compliant Weathering Solutions
UV Test Chambers — also known as UV Accelerated Weathering Testers — are precision laboratory instruments that simulate the damaging effects of sunlight, rain, and dew on materials in a controlled, repeatable, dramatically time-compressed environment. UV light represents only about 5% of natural sunlight but is responsible for the vast majority of polymer degradation — fading, cracking, chalking, loss of gloss, embrittlement, and mechanical property failure. By exposing samples to fluorescent UV lamps combined with controlled temperature, condensation, and water spray cycles, a modern UV test chamber compresses years of outdoor weathering into days or weeks — enabling manufacturers, QC laboratories, and R&D teams to predict real-world durability before products reach the market.
Qualitest offers a comprehensive UV weathering portfolio engineered for every laboratory size, budget, and compliance requirement. The flagship QualiUV™ 200 UV Light Accelerated Test Chamber is the full-feature floor-standing platform with US-made fluorescent UV lamps (UVA-340 or UVB-313, ~6,000-hour stable spectrum), automatic closed-loop irradiance control, high-precision Pt 100 temperature sensors, BST black-panel thermometer, a 12-nozzle water-spray system (6 nozzles per side) for heat-shock simulation, a unique condensation system that produces 100% relative humidity, an HD color touchscreen, and user-editable test programs with up to 10 segments each and storage for 6 programs. The compact QualiUV™ 100 is the economical benchtop counterpart — equipped with three 20W UVA or UVB lamps and customizable total illumination time, temperature, and spray duration — ideal for basic UV testing in small QC labs, teaching laboratories, and entry-level R&D. Complementing both chambers, the Irradiance Radiometer & Calibrator delivers precise reference calibration of UVB (313 nm) and UVA (340 nm) fluorescent lamps — ensuring that every chamber in a multi-unit laboratory produces consistent, comparable, audit-defensible irradiance readings.

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.
