Why Choose LIB UV Accelerated Machine

① Closed-Loop Irradiance Control

Automatic irradiance control keeps UV intensity stable throughout testing by compensating lamp aging and voltage changes. No manual adjustment needed, ensuring consistent and internationally accepted results.
One-touch radiometer calibration simplifies routine verification.

② UV Lamp Options

UVA-340: Simulates natural sunlight (295–365 nm), for outdoor weathering tests
UVB-313: Faster, more aggressive aging for rapid QC screening

Lamp life: 5000 hours, easy replacement and predictable maintenance.

③ Condensation & Spray Simulation

Bottom-heated water system creates true condensation (100% humidity) to simulate dew exposure.
Supports programmable water spray cycles to simulate rain and thermal shock.

Corrosion-resistant aluminum racks ensure stable sample positioning and uniform exposure.

Frequently Asked Questions (FAQ)

Q: How often should I calibrate the irradiance sensor?

A: We recommend calibration every 3–6 months, or per your internal SOP. Our system supports quick radiometer-based calibration.

Q: Can I use tap water for condensation?

A: No. Always use distilled or deionized water to prevent mineral deposits that can affect lamp performance and sample contamination.

Q: What's the difference between UVA-340 and UVB-313 lamps?

A: UVA-340 simulates natural sunlight (295–365 nm), ideal for realistic aging. UVB-313 uses shorter, harsher UV for faster comparison testing.

Q: How long does a typical weathering test take?

A: It depends on your standard and material. Common cycles range from 500 to 2,000 hours. Accelerated tests can replicate months or years of outdoor exposure.

Q: Do you offer installation and training?

A: Yes. We provide on-site installation, operator training, and digital manuals. Remote training via video call is also available.
