The UVA UVB UVC Lamp UV Accelerated Weathering Tester uses imported QUV fluorescent UV lamps, including UVA-340, UVB-313, and UVB-351, each selected to meet specific testing standards and application requirements. The lamps provide controlled spectral output in the 290–400 nm range, ensuring accurate reproduction of UV radiation responsible for material degradation. Lamp output remains stable over a service life of up to 5000 hours, minimizing spectral drift and maintaining consistent irradiance throughout long-term tests.
Engineering Benefits
1. Full-Spectrum UV Simulation: The tester supports UVA, UVB, and UVC fluorescent lamps with a spectral range of 290–400 nm, including common configurations such as UVA-340, UVB-313, and UVB-351. UV irradiance is adjustable from 0.3 to 20 W/m² (depending on wavelength), allowing compliance with multiple UV aging and weathering standards for plastics, coatings, rubber, and textiles.
2. Multi-Environment Aging Simulation: The chamber combines UV radiation, temperature control from ambient to 90 °C (±2 °C), humidity levels up to ≥95 % RH, condensation cycles, and an automated water spray system. Spray duration and intervals are programmable, enabling realistic simulation of daytime UV exposure, nighttime condensation, and rainfall within a single test cycle.
3. Stable and Accurate Control: An intelligent PID control system regulates temperature, UV irradiance, and spray cycles with continuous feedback from high-precision sensors. UV output is monitored in real time by an integrated UV irradiance radiometer, while Black Panel Temperature (BPT) is controlled typically between 35 °C and 80 °C, ensuring stable and repeatable test conditions throughout long-duration aging tests.
4. Efficient Sample Handling: The chamber is equipped with flat aluminum specimen holders supporting 50–56 standard specimens (75 × 150 mm) for uniform UV exposure. Customized holders are available for non-standard shapes and specimen thicknesses of up to 10 cm as standard, with optional designs supporting 20 cm or more, ensuring stable positioning during long-term testing.
5. User-Friendly Operation and Data Management: A programmable color touchscreen controller supports up to 120 test programs with 100 steps per program, enabling complex cyclic aging tests and unattended operation. Built-in USB and Ethernet interfaces allow test data export, remote monitoring, and traceability for quality control and compliance documentation.
6. Durable and Low-Maintenance Construction: The chamber interior is manufactured from SUS304 stainless steel, providing corrosion resistance under high humidity and UV exposure. The exterior uses coated steel for long-term durability. UV lamps with a service life of up to 5000 hours are easy to replace, while the circulating water system supports continuous spray operation for more than 72 hours, reducing maintenance frequency and operating costs.

Typical Tests
The UVA UVB UVC Lamp UV Accelerated Weathering Tester is commonly used to conduct accelerated UV aging tests at irradiance levels such as 0.3–1.5 W/m², high-temperature exposure up to 90 °C, and high-humidity aging at around 95 % RH. It supports lightfastness testing for textiles and coatings, simulating long-term sunlight exposure to evaluate color stability. Combined UV and water spray cycles are often used to study cracking, chalking, and surface degradation of plastics and painted components under realistic outdoor conditions.

FAQs
Q 1: How long can the chamber spray continuously if the water tank is full?
The water system is designed as a circulation system. Even without an external water supply connection, a full tank can support continuous operation and spraying for more than three days, meeting the requirements of long-term weathering tests.
Q 2: What is the maximum specimen thickness supported?
Standard sample holders support specimens up to approximately 10 cm thick. With customized racks, thicknesses of 20 cm or more can be accommodated.
Q 3: How is humidity generated and controlled?
Humidity is produced by heating water to generate steam, creating a high-humidity environment in line with testing standards. While humidity is not independently controlled to a precise setpoint, it effectively simulates realistic high-moisture outdoor conditions essential for weathering tests.
