Lisun UV-263LS UV Material Aging Test Chamber (RT~70℃, ≥90% RH)

Lisun UV-263LS UV Material Aging Test Chamber (RT~70℃, ≥90% RH)

The Lisun UV-263LS UV Material Aging Test Chamber is an optimal industrial solution designed to simulate the effects of sunlight, temperature, and humidity to evaluate the resistance to aging, fading, or material transformation of samples such as plastics, paints, rubber, building materials, and fabrics. The device operates based on accelerated environmental simulation methods, helping to thoroughly test durability without damaging the basic structure of the sample other than for aging purposes.

Outstanding Features

Comprehensive simulated UV irradiation system: The device is equipped with specialized UV fluorescent lamps that accurately simulate the spectrum of sunlight in the short-wave range, combined with a temperature and humidity control system (RT~70℃, ≥90% RH) to reproduce the harshest weather conditions.

Powerful aging test performance: Applying radiation energy combined with condensation and water spray cycles, the machine has the ability to accelerate material aging much faster than natural conditions, achieving extremely high evaluation efficiency for the fatigue durability of products before practical application.

Intelligent operation and environmental control system:

• Precise temperature and humidity control system: Helps stably maintain temperatures from room temperature to 70°C and relative humidity from 90% RH and above inside the test chamber.
• Combined exhaust and circulation system: Integrates specialized fans and ducts to balance humidity and temperature and automatically process gases generated during operation out to the safe environment.

Insulation materials and durable structure: The chamber walls use high-grade anti-corrosion materials combined with a thick insulation layer to retain heat and maintain stable humidity, protecting the safety of the outer shell and maximizing energy savings.

Advanced safety protection mechanism: The machine integrates smart features such as: over-temperature protection, over-current protection, water and electrical circuit overload protection, and an instant error alarm system, ensuring stable operation in continuous laboratories and factories.
