Yellow Resistance Test Chamber Simulate Ultraviolet Radiation and Solar Heat Testing Equipment

The Standard for Material Colorfastness Assessment

Beyond dedicated yellowing tests, this unit serves as a versatile accelerated aging chamber, offering exceptional value and operational flexibility in a single footprint. It is the ideal solution for manufacturers seeking to prevent costly product recalls due to premature discoloration or material failure.

Core Testing Capabilities: Simulating Real-World Degradation

1. Dual-Mode Functionality: operators can seamlessly switch between irradiation mode (UV focus) and temperature mode (thermal focus). This allows for isolated testing of photodegradation mechanisms or combined thermo-photo stress simulations, providing comprehensive data on material stability.

2. Premium UV Light Source: equipped with an imported OSRAM ULTRA VITALUX 300W lamp, the chamber delivers consistent, spectrally stable ultraviolet output that closely mimics natural sunlight. The programmable light timer supports continuous operation for up to 9,999 hours, enabling long-duration aging cycles without manual intervention.

3. Adjustable Exposure Geometry: the distance between the sample and the UV lamp is finely adjustable from 100mm to 300mm. This feature allows technicians to calibrate irradiance intensity according to specific test protocols or material sensitivity, ensuring precise replication of various environmental conditions.

4. Uniform Dynamic Rotation To eliminate shadowing and ensure even exposure, the chamber features a height-adjustable, perforated turntable (350mm diameter, 20kg max load). The rotation speed is adjustable between 3-15RPM, guaranteeing that every specimen receives uniform UV and thermal exposure for statistically reliable and repeatable results.

Advanced Control System & Intelligent Data Management

1. Industrial PLC+ Touchscreen Interface: the system integrates a high-performance XINJE XDS-series PLC with a 4.3-inch MCGS human machine interface(HMI). The flat-design UI provides real-time visualization of current temperature, setpoints, light-on duration, and remaining test time, making complex programming intuitive and efficient.

2. High Resolution Sensing &Control: utilizing a PT100 three-wire high-precision temperature sensor, the controller achieves 0.1℃ resolution and maintains a tight temperature deviation of ±3℃ across the operating range of RT+℃ to 80℃. Heating is regulated via solid-state relays (SSR) for smooth, contactless power control, eliminating mechanical wear and ensuring stable thermal performance.

3 Proprietary Software Ecosystem: the control software is independently developed by our engineering team and holds official software copyright certification. It supports flexible parameter programming, USB data export for historical analysis, and future firmware upgrades. The system’s scalable architecture allows for non-standard customization to meet unique testing workflows.

Industrial-Grade Construction & Safety Standards

1. Corrosion-Resistant Chamber: The interior is fabricated from mirror-finish stainless steel, offering superior UV reflectivity, chemical resistance, and effortless cleaning after tests. The exterior features a durable powder-coated finish that withstands harsh laboratory environments.

2. Optimized Air Circulation: A high-efficiency centrifugal circulation motor drives forced convection, rapidly homogenizing temperature distribution throughout the test space (500×600×500 mm). This ensures minimal thermal gradients and consistent test conditions.

3. Multi-Layer Safety Protection: Independent safety mechanisms include heating over-temperature cutoff, motor  thermal overload protection, and electrical safeguards against overload, short-circuit, and leakage. These systems operate autonomously to prevent equipment damage and ensure operator safety.
