How to Choose Light Fastness Tester: Water-Cooled and Air-Cooled
A Light Fastness Tester is a commonly used experimental device that simulates the solar radiation (particularly ultraviolet, visible, and infrared light) combined with environmental factors such as temperature and humidity to accelerate the aging process of materials or products, thereby evaluating their weather resistance, light resistance, and performance degradation. When selecting a Light Fastness Tester, users typically need to consider the cooling method (water-cooled or air-cooled).
Choosing Between Water-Cooled and Air-Cooled
GESTER water-cooled light weather fastness tester features a 4500W water-cooled xenon arc lamp system, accurately simulate sunlight spectrum. Irradiance auto- compensates system, control irradiance, temperature, and humidity timely through a closed loop. Ultrasonic humidification system makes spray water even and low noise. Saturated steam humidifying, industrial refrigerating machine dehumidifying, and close loop control the humidity. De-ionized water system to ensure purity of cooling water and spray water.
GESTER air-cooled xenon weathering test chamber uses an industrial-grade temperature control (air-cooled) system that can quickly and smoothly regulate the temperature inside the test chamber. To make the machine is more energy saving and environment friendly. The equipment can operate continuously for 1,000 hours and is highly reliable.
It is widely use in solar radiation simulation light color fastness, light perspiration color fastness and light aging test of rubber, plastic, coating, petrochemical industry, car, textile industrial products and other materials. It through simulate illumination, exposed to the rain, mist spraying, alternating light and dark, temperature and humidity climates conditions to test material products’ color fading, aging, transmittance, peeling, hardness, softness and other performance changes.
Light Fastness Testing Machine apply to light color fastness, anti-climate color fastness, light & perspiration color fastness and light aging tests of textile, paint, dye, coating, rubber, plastic, wood floor, paper and other materials, it have anti-climate functions of exposing to the rain, revolution and mist spraying.
What is the difference between light fastness tester and UV light discoloration test chamber?
Light fastness testing machines and UV light discoloration test chambers differ in principle, method, application, and spectral range. Below is a comparison between them:
Working Principle
The light fastness tester can simulate sunlight. It includes ultraviolet, visible, and infrared light. It fully simulates natural lighting conditions. This light weather fastness tester simulates the entire solar spectrum, including ultraviolet, visible, and infrared light. It uses xenon arc lamps. Lightfastness testers are widely used for ageing tests in real-world environments.
On the other hand, the UV ageing test chamber simulates the harmful UV rays in sunlight. Its spectrum is more uniform, but the ageing intensity is higher. This equipment simulates the destructive effects of sunlight on materials. It uses specific fluorescent UV lamps that produce the most impactful UV rays.
The UV Light Discoloration Test Chamber GT-KD02 is a specialized machine designed to test the discoloration resistance of shoe materials and other related products.
This versatile UV Light Discoloration Tester is not limited to discoloration tests. It can also function as an aging tester and dyeing oven, making it a multi-functional solution for laboratories and manufacturers.
Advantages of Xenon Weathering Test Chambers?
Light fastness testers provide multiple benefits, including high reliability, accelerated aging, precise control, and a wide range of applications
High reliability:
Light fastness testers can precisely control the exposure of materials. They simulate real-world conditions, thereby yielding more reliable data.
Accelerated aging:
Light fastness testing machines can perform material ageing tests more quickly. This reduces costs and improves efficiency. Lightfastness testing is much faster than natural environment testing. It can be several times, or even ten times, faster.
Precise Control
Light weather fastness testers can simulate light of different wavelengths, intensities, and temperatures, and precisely control these factors to make ageing test results more accurate and reliable.
Wide Application:
Xenon weathering test chambers are used in materials science, chemistry, and the automotive industry. For example, in the automotive industry, light fastness testers can simulate harsh weather conditions such as sunlight, rain, and cold. They can then test the durability of cars, parts, and components. Additionally, they have many applications in building materials, plastics, and rubber.
