In the field of materials science and product quality inspection, xenon weatherometers play a crucial role. They simulate solar radiation, temperature, humidity, and rainfall, performing accelerated aging tests on materials and products to evaluate weather resistance and service life. This article delves into the principle, structure, characteristics, application fields, and operating steps of the xenon weatherometer, helping you fully understand this key testing equipment.

Ⅰ. Principle of Xenon Weatherometer – Simulating Natural Sunlight with Precision

The xenon weatherometer uses xenon lamps (1500–3000 W, 280–800 nm) to reproduce the full spectrum of sunlight, including ultraviolet, visible, and infrared radiation. By precisely controlling irradiation intensity, temperature (–20°C to +80°C ±0.5°C), humidity (20–98% RH ±2%), and spray rainfall (0.1–2 mm/min), it can mimic natural climatic conditions across different regions and seasons.

During testing, the material is exposed to xenon lamp radiation, combined with temperature/humidity cycles and optional rainfall, accelerating the aging process to replicate years of outdoor exposure in just weeks.
